In the diaphragm, an upper surface plate contact portion, which is a region defining the opening and being in contact with the upper surface plate, includes a deformed portion elastically deformed to protrude toward the lower surface plate side by contact with a support plate. The deformed portion is in contact with a sliding member located on the lower surface plate side when viewed from the deformed portion.
