Light emitting device

A light emitting device comprising:

• a first substrate comprising:
• a first lead,
• a second lead positioned apart from the first lead, and
• a resin part holding the first lead and the second lead in place;
• a second substrate disposed on an upper face of the second lead, the second substrate comprising:
• a base, and
• a first conducting part disposed on an upper face of the base;
• a light emitting element disposed on the second substrate and electrically connected to the first conducting part;
• a first wire electrically connecting the first lead and the first conducting part;
• and
• a wall part straddling and covering an upper face of the first lead and an upper face of the second lead,
• wherein a height of the wall part is less than a height of the second substrate, and
• wherein the resin part comprises a first cover resin part surrounded by the wall part in a top view and covering the upper face of the first lead, the first cover resin part having an inner edge with a first end that terminates at a first inner surface of the wall part and a second end that terminates at a second inner surface of the wall part, the first inner surface being perpendicular to the second inner surface wherein the first cover resin part does not overlap the second lead.
