Abstract

A wrapping sheet is provided to keep electronic parts in an excellent dry condition and let static electricity caused by the friction of materials release to the outside. The wrapping sheet for enveloping electronic parts comprises an air permeable sheet at one side, an air non-permeable sheet with a conductive layer on the other side, separate pouchy portions formed between both the sheets, and silica gel and conductive foam beads enclosed in each separate pouchy portion.
