CASE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a thin case at low cost in which the required strength is ensured.

SOLUTION: The case 1 includes: a cover 2, which is three-dimensionally formed by bending a blank 12 consisting of a sheet material with two or more areas segmented by a bending line 13 along the bending line 13; and a bone member 3 fused with the cover 2 by the injection molding of a synthetic resin to reinforce the cover 2. The bone member 3 connects end rims while extending along at least a pair of adjacent end rims in a different area of the cover 2.
