A through anchor in which residual stress caused by thermal contraction is dispersed so as to reduce risk of crack formation in a resin molding portion. The through anchor includes a metal plate and a resin molding portion covering a portion of the metal plate. Usually, residual stress due to thermal contraction (shrinkage) differences between the resin molding portion and the metal plate is high in regions near both ends of the boundary between the resin molding portion and the metal plate.
