摘要：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 crosssection 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 componentsare secured in place on the metal plate separate from and independent of each other byvirtue of residual thermal stress produced by the difference in the coefficient of thermalexpansion between the resin portions and the metal plate in such a manner that a radiallyoriented residual thermal stress in each resin portion is symmetrical with respect to acenter axis of one of the resin components.
