Abstract
A valve case, which is a metal component, and an outer shell portion of a cylinder head cover, which is a resin component, are joined together through a seal material. First, a recess formed in the valve case is filled with a seal material in a liquid form. A skin layer is then formed by curing the surface of the seal material. Subsequently, the outer shell portion is formed by supplying a synthetic resin material onto the valve case in such a manner as to cover the skin layer, which is provided on the surface of a non-cured portion of the seal material. At this stage, the skin layer is broken by supply pressure of the synthetic resin material and thus the synthetic resin material and the non-cured portion of the seal material are joined together as an integral body.
