<p>PROBLEM TO BE SOLVED: To make feasible of thinning and light weighting of a solid electronic device. SOLUTION: A substrate 3 mounted with an electronic component contained in a case body composed of a pair of plastic made outer shells 1, 2, divided into outside and inside. The honeycomb cores 4 are integrally molded of plastic in the parts away from the electronic component 13 on the inner surface of the outer shells 1, 2. Besides, recessions 5 encircled by stepped parts in the shape corresponding to the outer periphery of the honeycomb cores 4 are provided on the outside and inside of the substrate 3. In such a constitution, the outer shells 1, 2 are joined together with the front ends of respectively provided honeycomb cores 4 engaged with the recessions 5.</p> |
