続された配線基板３をこの金属パネル】内に挿入する。In these figures, the memory card of this embodiment has a large number of electrical and electronic components 2 such as memories on the upper main surface of the wiring board 3.
is mounted, and further a spacer 4 is fixed to the lower main surface and the side part. A metal panel 1 whose upper lens surface side and lower main surface side are integrally molded is placed over the metal panel 1, and the wiring board 3 connected to the connector 7 is inserted into this metal panel, as shown in FIG.
この金属パネルｌの製造は、圧延加工もしくは溶接等の
技術を用いる。コネクタ７と、金属パネル１との固定法
は、接着材を用いるか、まだは機械的にかしめる。This metal panel 1 is manufactured using techniques such as rolling or welding. The connector 7 and the metal panel 1 are fixed by using an adhesive or mechanically caulking.
本実施例の金属パネル１は、特にメモリカードの３側面
すべてが同一金属で形成される必要が無い場合、−側面

メモリカードの側面で行う必要は無く、必要に応じて上
主面若しくけ下主面の適当な場所で行っても良い。In the metal panel 1 of this embodiment, especially when all three sides of the memory card do not need to be formed of the same metal, it is preferable that all sides other than the - side are welded or mechanically fixed. The two metal panels in the figure are mechanically fixed. Incidentally, such fixing does not necessarily have to be done on the side surface of the memory card, but may be done at an appropriate location on the upper main surface or the lower main surface of the shackles, if necessary.
