摘要
A semiconductor chip is mounted on a flexible wiring board through the interposition of an elastmer. The flexible wiring board is made up of a tape on which wiring is fixed. A part of the wiring is projected beyond the edge of the tape, extended in the direction of the thickness of the elastmer and connected to an electrode of the semiconductor chip. The edge of the tape beyond which the wiring is projected protrudes beyond the edge of the elastmer by a length no smaller than the thickness of the elastmer.
