Abstract
A copper foil sheet is pasted onto the surface of a semiconductor module case to shield it from static electricity and noise. The sheet is provided with cross-cut lines corresponding to the positions of protruding parts on the surface of the case such that the sheet can be pasted along the contours of these protruding parts to improve its shielding effects.
