Abstract: A light emitting device includes a flexible substrate, a light emitting element, a conductive connecting material and a first holding member. The flexible substrate includes a flexible base and a wire. The first holding member is arranged on an opposite side surface to a surface of a side of the substrate on which the light emitting element is mounted. The first holding member surrounds a region corresponding to a region on the substrate including the light emitting element and the conductive connecting material in a plan view. The first holding member is arranged adjacent to the wire. The first holding member includes an inner region arranged on an inner side of the first holding member, and having higher rigidity than rigidity of the flexible base, and an outer region arranged adjacent to the inner region outside the inner region, and having lower rigidity than rigidity of the inner region.

Abstract: A light emitting device includes: a base body including two conductive members, a resin body, and a fiber member placed inside the resin body, and a light-emitting element. The resin body includes an isolation section located between the two conductive members, and includes a pair of sandwiching portions sandwiching the isolation section. The fiber member has a length which is greater than a distance between the two conductive members, and is located at least in an adjoining region of at least one of the pair of sandwiching portions, the adjoining region adjoining the isolation section. In the adjoining region, the fiber member extends in a direction which is non-orthogonal to a direction in which that the pair of sandwiching portions extend.

Abstract: A light emitting element mounting base member for mounting a light emitting element is provided that includes electrical conductor cores, light-reflecting insulating members, and light blocking resin. The insulating members each cover a lateral surface of each of the electrical conductor cores. The insulating members have a reflectivity of 70% or more to light emission wavelength of the light emitting element in a range of 440 nm to 630 nm. The light blocking resin joins at least two insulating members, and is capable of blocking light from the light emitting element by reflecting or absorbing the light. At least one upper surface of the electrical conductor cores, at least one lower surface of the electrical conductor cores are exposed from the insulating members and the light blocking resin respectively.
