PROBLEM TO BE SOLVED: To provide a speaker having a power feeder part structure excellent in reliability. SOLUTION: This speaker has a diaphragm; a voice coil bobbin bonded on the lower end part of the diaphragm; a voice coil wound around the lower end part of the voice coil bobbin; and an edge whose one end is fixed near a bonding portion between the diaphragm and the voice coil bobbin, and the other end is fixed to a frame. The edge comprises a foamed rubber and one or a plurality of flexible conductive substrates disposed on the inside or on the external surface of the foamed rubber so as to be fixed to the foamed rubber, and one end of each of these conductive substrates is electrically connected to the winding end of the voice coil and the other end is electrically connected to an input terminal.
