Abstract

The device bends readily and safely without a sealing resin peeling off or a breakage in a wire. In an LED columnar light emitting devicein which a plurality of two conductive regionsandcorresponding to the ± polarities are provided in the columnar direction on a film wiring board, each light emitting element is connected to and installed on the plurality of two conductive regionsand, and each LED chip, as each light emitting element, is sealed above with a transparent sealing resin, notch sectionsandA are formed on both outer sides of two plated linesas opening sections between the two conductive regionsandand another two conductive regionsandadjacent thereto in the columnar direction.
