ABSTRACT:
A method of manufacturing a casing for electronic apparatus use in which metal and resin are subjected to a hybrid formation, so that the mechanical strength of the casing is improved and the thickness is reduced so as to reduce the weight. An electronic apparatus casing having a rib (16) and boss (18) is manufactured when metal (10) and resin (12) are integrally formed. Adhesive (14) is coated on the metal, and after the coated adhesive has been dried, the resin (12) is injected onto the adhesive layer from a portion which composes the rib or boss, so that the metal and resin are subjected to a hybrid formation.
