There is provided a speaker allowing an air in a space between a diaphragm and a frame not to leak outside, and allowing connecting wires electrically connected to the voice coil to be guided out to an outside. A speaker I includes: a frame 4; a magnetic circuit unit 2; a vibrating unit 3; and a wiring structure unit 5. A hole 28 is formed on the frame 4. The magnetic circuit unit 2 is attached to the frame 4. The vibrating unit 3 is received in the frame 4, and includes diaphragms 14, 15 vibrated by the magnetic circuit unit 2. An air in a space surrounded by the diaphragms 14, 15 and the frame 4 is sealed. The wiring structure unit 5 includes a tube member 38, into which lead wires 37 are inserted. The tube member 38 is pressed into a hole 28, and guides the lead wires 37 to an outside of the space.
