Abstract:
1. A semiconductor device in which a semiconductor element is mounted on a flexible wiring substrate having a film-like shape and a wiring pattern thereon, wherein: a sealing resin fills a gap between the flexible wiring substrate and the semiconductor element, the sealing resin protecting the semiconductor element; a resin trace and peripheral resin portions are formed when the sealing resin is applied along at least one longitudinal side of the semiconductor element via a nozzle; the resin trace remains on an area through which the sealing resin is applied via the nozzle and the resin trace is formed only at the one longitudinal side of the semiconductor element; and the resin trace is 0.1 to 1.0 mm in width and not more than 10 μm in thickness.
