The present invention provides a diaphragm for a speaker that is excellent in processability, easy to manufacture, has an appropriate elasticity, is excellent in low-frequency reproduction, and can be used at a high input, and a speaker using the same. To do. SOLUTION: Two polymer layers, three low molecular layers arranged in close contact with both surfaces thereof, and a skin layer arranged in close contact with a surface opposite to the contact surface of the polymer layer of the low molecular layer This is achieved by a speaker diaphragm.
