Patent ID: 7626832

Claim:
An electromagnetic wave shield case comprising: a shield case body covering electronic parts on a circuit board, said shield case body comprising an upper surface and side surfaces that collectively form a single continuous body having a single lower opening delimited by said side surfaces; and a flange formed integrally with said shield case body, wherein the entirety of said shield case body and said flange are made of nonmagnetic metallic glass having a fracture strength/elastic constant value of more than 0.012, wherein said flange is elastically deformed to be grounded to a grounding conduction portion on said circuit board to prevent a leakage of electromagnetic waves to outside of said electromagnetic wave shield case, wherein said flange is tapered at an angle less than 90° prior to being elastically deformed, and wherein said shield case body and said flange provide a shield amount SE of at least −60 dB.
