ABSTRACT:
A molded part including a metal plate formed with a plurality of through holes, a plurality of resin portions connected to a resin filled in the through holes and protruding on opposite sides of the metal plate, the resin portions having a planar cross section larger than a cross section of the through holes, and a plurality of resin components each integrally formed with one of the resin portions. The resin components are secured in place on the metal plate separate from and independent of each other by virtue of residual thermal stress produced by the difference in the coefficient of thermal expansion between the resin portions and the metal plate in such a manner that a radially oriented residual thermal stress in each resin portion is symmetrical with respect to a center axis of one of the resin components.
