An air pump that reciprocates a diaphragm provided in a pump chamber by electromagnetic vibration, wherein a fitting portion is formed on the peripheral edge of the diaphragm, and a fitting portion into which the fitting portion can be fitted is provided. The pump includes a frame in which a fitting groove is formed, and a pump chamber casing in which a fitting convex part that can fit into the fitting groove is formed, and the fitting part of the diaphragm is fitted in the fitting groove of the frame, Furthermore, the diaphragm type air pump is configured to apply tension to expand the diaphragm radially outward by fitting and fixing the fitting convex portion of the casing into the fitting groove, and maintain the tension at a predetermined value. 2. The diaphragm according to claim 1, wherein the tension applied to the diaphragm can be adjusted by adjusting the depth at which the fitting protrusion of the casing fits into the fitting groove of the frame. type air pump.
