PROBLEM TO BE SOLVED: To provide a diaphragm for a loudspeaker subjected to a molding process using an olefin-based resin, having a relatively-large specific elastic modulus, and capable of increasing internal loss, and suppressing temporal deformation after molding. SOLUTION: A base body contains, as main constituents: a first resin material being an olefin-based resin; and a second resin material, wherein the density of the first resin material is larger than that of the second resin material. The base body is large in a specific elastic modulus and internal loss relative to those of a base body for comparison having a shape substantially identical to that of the base body and formed of the first resin material.
