Light emitting device

A light emitting device, comprising:

• a substrate including:
• a base member including a front surface extending in a first direction as a longer direction and a second direction as a shorter direction, a rear surface located opposite to the front surface, a bottom surface adjacent to and perpendicular to the front surface, and a top surface located opposite to the bottom surface, and
• a first wiring portion located on the front surface, and a second wiring portion located on the rear surface;
• a first light emitting element electrically connected with the first wiring portion and placed on the first wiring portion;
• a second light emitting element disposed adjacent along the first direction to the first light emitting element;
• a first light-transmissive member including a first surface opposing to the first light emitting element and a second surface located opposite to the first surface;
• and
• a cover member including a third surface located farther away from the front surface of the base member than is the second surface in a third direction which is perpendicular to the first and second directions;
• wherein:
• the base member has a recessed portion opened on the rear surface and the bottom surface;
• and
• the substrate includes a third wiring portion covering an inner wall of the recessed portion.
