Abstract: The objective of the present invention is to provide a shield method and shield material enabling to hold a flexibility degree with an enclosure shape and to make electronic component enclosures small and thin types. The shield method for electronic component enclosures in the present invention comprises a process in which a conductive layer is formed at a basic sheet and a shield sheet forming a non-hardening adhesive layer at the counter face to the basic layer is punched out to fit in individual electronic component enclosures for forming the shield materials, a process in which the shield material is attached to said electronic component enclosure, and a process in which a conductive adhesive is formed between a ground electrode set at said electronic component enclosure and the conductive layer to connect electrically.
