Abstract

A case for an electronic apparatus and a method of manufacturing the case for an electronic apparatus are disclosed, in which a working process can be simplified, the manufacturing cost can be reduced, and productivity can be improved. The case for an electronic apparatus can be manufactured by the steps of providing a case body; arranging the case body inside a mold; injecting a melted resin between a surface of the case body and the mold; and forming a thin film injection layer on the surface of the case body through double injection molding by solidifying the melted resin.
