The body side part fitting part is a linear recess extending in a vertical direction, and is provided in a region facing the peripheral edge part on a main surface 210 of the filter plate body. The body side part fitting part is fitted to the sheet side part fitting part in a press-fit state. The engagement structure has a body engagement part 261 and a sheet engagement part 262, and prevents a part of the sheet side part fitting part from moving in the vertical direction to the body side part fitting part along partial extension/contraction in the vertical direction in the diaphragm sheet.
