Abstract: A damper for a speaker includes a first fiber having a tensile strength of equal to or larger than 17 cN/dtex and a second fiber having a tensile elastic modulus of equal to or smaller than 200 cN/dtex. Thereby, necessary tensile strength and elasticity can be ensured. In addition, the ratio of the first fiber to the total amount of the first and second fibers is from 10% to 90%. If the ratio of the first fiber is smaller than 10%, the necessary tensile strength and elasticity cannot be obtained. Meanwhile, if the ratio of the first fiber becomes larger than 90%, punching property at the time of damper manufacture deteriorates. Thus, it is preferred that the first fiber is included at the above ratio.
