Abstract
A scroll compressor is constructed by combining a stationary scroll and an orbiting scroll formed by erecting a scroll-shape wrap upright on a base plate meshing with each other. A scroll member constructing the stationary scroll or the orbiting scroll is constructed of an inner layer memberforming a core metal and an outer layer memberarranged so as to surround the inner layer member and forming an outer layer part, the inner layer member is constructed of a material with higher modulus of elasticity than that of the outer layer member, and separation prevention parts (uneven parts, depressions, or holes) preventing the inner layer member and the outer layer member from separating with each other due to difference in coefficient of thermal expansion thereof are arranged in the inner layer member.
