At least one of the first and second communication sections includes a plurality of fine holes (31). A vortex chamber (25b) is disposed at a portion of the main body flow passage, which is connected to at least one of the first and second communication sections, is configured to form a swirling flow of liquid according to a flow velocity of liquid flowing from the other of the first and second communication sections, and causes the liquid of the swirling flow to flow out through the plurality of fine holes. A barrier wall (36a) in which the plurality of fine holes are formed extends in a direction across a vortex axis along a central axis (O2) of the vortex chamber. Among the plurality of fine holes, fine holes located on an inner side in a swirl radial direction across the vortex axis in a top view of the barrier wall have a lower flow resistance than fine holes located on an outer side in the swirl radial direction.
