ABSTRACT:
An objective of the present invention is to form a hyper-elastic flange integrally within a shield case body around a periphery thereof while decreasing an occupied area for grounding. The shield case2according to the present invention is disposed to cover electronic parts6on a circuit board1,and which has a flange7formed integrally therewith so as to contact with a metallic ground line3on the circuit board1. The flange7is elastically deformed to be grounded, thus a leakage of electromagnetic waves to the outside of the shield case2is prevented. The flange7is made of metallic glass. By forming the flange7from metallic glass, a displacement due to viscous flowing on the atomic level, which is different from a plastic deformation, can be utilized, and thus a high precision flange can be formed without a spring-back.
