摘要： Provided is an internal pressure adjustment member to be attached to an outer surface of a housing, the member having high air permeability even when a differential pressure that can be generated between the inside and the outside of a housing to which the internal pressure adjustment member is attached is small, and inhibiting damage to the member and a reduction in the air permeability of the member due to coming soil and mud. The internal pressure adjustment member includes: a filter portion including a net-like or mesh-like support layer and first and second porous polytetrafluoroethylene (PTFE) membranes laminated on the support layer such that the support layer is interposed therebetween, the first porous PTFE membrane being exposed on one surface of the filter portion, the second porous PTFE membrane being exposed on another surface of the filter portion; and an adhesive portion, formed on the one surface of the filter portion, for attaching the filter portion to the outer surface of the housing. The first porous PTFE membrane and the second porous PTFE membrane each have an average pore diameter of 2.0 μm or more, the filter portion has a thickness of 140 μm or less, and the filter portion has a density of 0.60 g/cm3 or less.

摘要： The present invention provides a ventilation member attachable to a housing having an opening for ventilation. This ventilation member includes: a support including: a base portion adapted to form an air passage between an interior space and an exterior space of the housing; and a leg portion extending from the base portion and adapted to be fitted into the opening; an air-permeable membrane disposed on the support to cover the air passage; and a sealing member made of a resin and placed at a root of the leg portion of the support. This sealing member has a compression set of 10% or less when measured under conditions of a test temperature of 100° C. and a test time of 100 hours in accordance with JIS K 6262. According to the present invention, it is possible to provide a ventilation member suitable for preventing water from entering a housing even during a high-pressure car wash test using high-temperature water.

摘要： Provided is a plate-shaped composite material which can sufficiently exhibit an interference effect between antenna elements when utilized as, for example, a substrate of a microstrip patch antenna. The interference effect between the antenna elements can be sufficiently exhibited by controlling the composite material so that, when the material is divided into a plurality of regions, a standard deviation of density values of the respective regions is kept at a certain value or less.

摘要： A housing kit (90) includes a housing body (20) and a ventilation member (10). The housing body (20) has a vent hole (21). The ventilation member (10) has a leg portion (26). The leg portion (26) is a portion adapted to be inserted into the vent hole (21). The housing body (20) has an inner peripheral surface (23) that defines the vent hole (21). The inner peripheral surface (23) includes a first rounded segment (23R1), a first straight segment (23S1),ounded segment (23R2), and a second straight segment (23S2) that are formed in order from an exterior space (24) side to an interior space (22) side of the housing body (20). The first rounded segment (23R1) and the second rounded segment (23R2) each form a curve convex toward a central axis (O) of the vent hole (21) in a cross section of the housing body (20) including the central axis (O). The first straight segment (23S1) and the second straight segment (23S2) each form a straight line in this cross section.
