PROBLEM TO BE SOLVED: To provide a diaphragm for speaker and a speaker using the same which have a high strength and moreover an excellent treble vibration characteristic. SOLUTION: The diaphragm for speaker comprise a woven cloth 1 in which an impregnated thermosetting resin is cured, and a paper plate 2 integrated with the back face side of this woven cloth 1 by thermocompression bonding, and the woven cloth 1 shows a weave pattern on the surface side. As the woven cloth 1 is used, its strength is high, and also as the thermosetting resin impregnated in this woven cloth 1 is cured by heat, its hardness is high. Thus, it is possible to provide the diaphragm for speaker and the speaker using the same which have the excellent treble vibration characteristic. COPYRIGHT: (C)2009,JPO&INPIT
