Abstract: A connected body includes first and second light emitting devices and a connecting member. The first light emitting device includes a flexible first substrate member extending in a predetermined direction, a first light emitting element arranged on the first substrate member, and an electronic component arranged on a first end portion of the first substrate member with respect to the predetermined direction. The second light emitting device includes a flexible second substrate member extending in the predetermined direction, and a second light emitting element arranged on the second substrate member. The connecting member connecting the first end portion of the first substrate member and a second end portion of the second substrate member adjacent to the first end portion of the first substrate. A position of at least a part of the connecting member in the predetermined direction overlaps a position of the electronic component in the predetermined direction.

Abstract: Provided is a light emitting device in which deterioration of the substrate member can be reduced. The light emitting device includes a base member mainly made of a resin, a plurality of wiring portions and arranged on the base member via an adhesive agent, a groove portion defined between adjacent wiring portions, and at least one light emitting element which is disposed straddling at least a part of the groove portion. The adhesive agent is applied covering the base member from the groove portion, and contains a light-shielding member. The light-shielding member shields the base member from light, for example at a specific wavelength, emitted from the at least one light emitting element.
