A speaker device includes a connecting member having a groove supporting an inner peripheral edge portion of a diaphragm. The groove is formed at an area in the vicinity of an upper end of an outer peripheral wall of a cylindrical portion, and is formed on the outer peripheral wall of the cylindrical portion along the circumferential direction. An adhesive is applied to the inside of the groove, and the inner peripheral edge portion of the diaphragm is inserted therein. Therefore, the inner peripheral edge portion of the diaphragm is securely fixed to the groove. According to such the structure, the area in the vicinity of the inner peripheral edge portion of the diaphragm is disposed not above the upper end surface of the connecting member and at the area in the vicinity of the lower end surface, but at a position substantially as high as the upper end surface.
