PROBLEM TO BE SOLVED: To reduce the deformation or distortion of a diaphragm for an electroacoustic transducer with a multilayer structure having surface diaphragm layers composed of woven fabrics, and to provide the diaphragm with the multilayer structure in high quality, etc. SOLUTION: The diaphragm 1 for the electroacoustic transducer has the multilayer structure where an intermediate diaphragm layer 5 is formed between surface layers 31, 32. The surface layers 31, 32 are composed of the woven fabrics and integrally formed by deviating the fiber axial directions of the surface layers 31, 32 in a circumferential direction by prescribed angle. It is preferable that the fiber axial directions of the surface layers 31, 32 composed of the biaxial woven fabrics are deviated in the circumferential direction by substantially 45°.
