    • An object is to provide an electromagnetic actuator that is highly resistant to corrosion and also capable of having high suction power, even in a condition where part of the electromagnetic actuator touches a corrosive liquid. An electromagnetic actuator 50 according to this invention is incorporated into a device using a corrosive liquid 17. The electromagnetic actuator 50 is characterized by including a magnetic pole piece 1; an outer yoke 6; a bottom yoke 5; a bobbin coil 2; a stepped portion 6a that is formed on an outer surface of the outer yoke 6; a waterproof portion 8 that prevents the corrosive liquid 17 from entering at least where the bobbin coil 2 and the magnetic pole piece 1 are; a movable plate 12 that is placed in the corrosive liquid 17 to form a magnetic circuit together with the magnetic pole piece 1, the outer yoke 6, and the bottom yoke 5, The movable plate 12 is stored in a space 14 created either in the electromagnetic actuator 50 or between the device using the corrosive liquid 17 and the electromagnetic actuator 50. The outer yoke 6 is incorporated into the device using the corrosive liquid 17, on a reduced diameter side from the stepped portion 6a.

    • A substrate (3) has a build-up layer in which insulating layers containing a resin and conductor interconnect layers (312) are alternately laminated and the conductor interconnect layers (312) are mutually connected through the conductor layer formed in a via-hole of the insulating layer. A conductor interconnect layer (312D) arranged on the outermost surface side of a substrate among the conductor interconnect layers (312) has a plurality of signal lines (312D1) formed in a signal line arrangement area (A) and extended in a predetermined direction. When αsig-x represents a coefficient of thermal expansion in a direction substantially parallel to the signal lines (312D1) in the signal line arrangement area (A) having the signal lines (312D1) as determined by a laser speckle method and αsig-y represents a coefficient of thermal expansion in a direction substantially orthogonal to the signal lines as determined by a laser speckle method, a dependence rate in the signal line direction of a coefficient of thermal expansion represented by the following equation is 25 or less. Dependence rate in the signal line direction of the coefficient of thermal expansion=(|αsig-y−αsig-x|/αsig-x)×100.
