Claim:
1. An LED module comprising: a first and a second LED chips spaced apart from each other; a first lead including a first die bonding portion on which the first LED chip is mounted; a second lead including a second die bonding portion on which the second LED chip is mounted; and a case covering a part of each of the first lead and the second lead, wherein the first lead includes a first outer portion projecting from the case to an outside of the LED module, the first outer portion having a first mounting terminal surface for surface-mounting and a first reverse surface opposite to the first mounting terminal surface, the second lead includes a second outer portion projecting from the case to the outside of the LED module, the second outer portion having a second mounting terminal surface for surface-mounting and a second reverse surface opposite to the second mounting terminal surface, the case is provided with a recess that exposes at least a part of each of the first reverse surface and the second reverse surface, as viewed from a side opposite to a direction in which the first mounting terminal surface and the second mounting terminal surface face, the first LED chip and the second LED chip emit light in a direction parallel to the first mounting terminal surface and the second mounting terminal surface, the LED module further comprises a third LED chip, a third lead, a fourth lead and a diode chip mounted on the fourth lead, the third LED chip is disposed between the first LED chip and the second LED chip in a direction in which the first and the second LED chips are spaced apart from each other, and the third LED chip is disposed at a position spaced apart from a straight line connecting the first LED chip and the second LED chip, the third lead includes: a third die bonding portion on which the third LED chip is mounted; a third mounting terminal surface for surface-mounting; and a third reverse surface opposite to the third mounting terminal surface, as viewed in the direction in which the first mounting terminal surface and the second mounting terminal surface face, one of the first mounting terminal surface and the second mounting terminal surface is disposed between the third mounting terminal surface and the other one of the first mounting terminal surface and the second mounting terminal surface, the fourth lead has a first edge, a second edge and a third edge, the second edge being parallel to the first edge and facing an opposite side of the diode chip, the third edge connecting the first edge and the second edge each other, and the second lead comprises a protruding portion, the second edge of the fourth lead facing the protruding portion.
