摘要
An edge portion of a diaphragm is configured such that multiple recessed ribs formed by recessing of a raised surface are provided in an inclination direction inclined with respect to a radial line passing through a center point and are arranged rotationally symmetrically, and among the recessed ribs and a fixing portion defined on the outermost peripheral side of the diaphragm, defines an outer peripheral edge portion at which no recessed ribs are formed. A voice coil is coupled to a voice coil attachment portion. A lead line is fixed with a first adhesive forming a first adhesive layer along a valley portion defined between a certain recessed rib and an adjacent recessed rib thereof on a back side of the edge portion, and is further fixed with a second adhesive forming a second adhesive layer with the lead line being curved along the outer peripheral edge portion.
