増を招くという問題があった。2. Description of the Related Art Conventionally, metal members have been used for structural members such as vehicle parts and office machines. As such a metal member, a metal member having a groove shape, a lip groove shape, or a hat shape is usually used in order to reduce the weight.
However, the metal member having the above-described shape has a low rigidity in the opening due to the shape, and the opening is deformed by a load particularly in a portion where strength is required. Therefore, a metal member having a rectangular cross section is used. In addition, the rigidity is improved by providing a reinforcing rib made of a metal member inside the opening. Therefore, there has been a problem in that costs and weight are increased due to an increase in processes such as welding.

The resin member has a lower strength than the metal member, and particularly has a low rigidity, so that there is a problem that it cannot be used in a portion where strength is required.

According to this method, the through holes are provided in the metal member, and the reinforcing ribs made of the metal member and the resin member are connected by insert molding the resin. Therefore, there is a problem that a high residual stress remains between the metal and the resin due to the difference in molding shrinkage and the linear expansion coefficient, which leads to deterioration in product quality and reliability. Further, there is also a problem that a manufacturing facility for insert molding is required and the cycle time becomes long due to the thermal resistance between the insert metal and the mold.
