摘要

A compound ( 1 ) is manufactured which has a metal outer part ( 3 ) having a hollow space ( 2 ) and a content material ( 4 ) formed in the hollow space ( 2 ). Namely, manufacture is made by including an outer part forming step to form an outer part and a content material forming step to form a content material ( 4 ) in the hollow space ( 2 ) by using a metal matrix melt to be die-molded and a filler contained in the melt. The outer part ( 3 ) has a desired exterior form. Meanwhile, the content material ( 4 ) is formed in a state the hollow space ( 2 ) is filled in order to lighten the weight and improve the strength of the compound ( 1 ).
