PROBLEM TO BE SOLVED: To provide a light-emitting element module capable of releasing heat from an incorporated light-emitting element more efficiently and utilizing light emitted from the light-emitting element effectively.SOLUTION: A light-emitting element module A1 comprises a first lead 1, a second lead 2 separated from the first lead 1, a light-emitting element unit 3 including a light-emitting element having a first electrode terminal 31 electrically connected to the first lead 1 and a second electrode terminal 32 electrically connected to the second lead 2 via a wire 52, and a supporting member 6 for supporting the first and second leads 1 and 2. The first lead 1 has a die bonding section 11 having one surface in a thickness direction z on which the light-emitting element unit 3 is mounted and the other surface in contact with the supporting member 6. The die bonding section 11 has an opening section 11a penetrating in the thickness direction z and at least a part of the opening section 11a overlaps with a part of the light-emitting element unit 3 when seen from the thickness direction z. |
