Abstract
A light emitting module (1) comprises a module substrate (2), a light emitting diode string (31), and a sealing member (48). The light emitting diode string (31) includes light emitting diode elements (32) and bonding wires (37) which connect the light emitting diode elements (32). The light emitting diode element (32) has a pair of element electrodes (33, 34) and has a rectangular shape extending in a direction along which the element electrodes (33, 34) are aligned. The sealing member (48) is laminated on the module substrate (2) to seal the light emitting diode string (31). The light emitting diode elements (32) are arranged at intervals in a direction crossing the direction along which the element electrodes (33, 34) are aligned, and the element electrodes (33, 34) with the same polarity are aligned to be adjacent to each other in an arrangement direction of the light emitting diode elements (32) between the light emitting diode elements (32) adjacent to each other. Each bonding wire (37) is obliquely wired with respect to the arrangement direction of the light emitting diode elements (32) to connect the element electrodes (33, 34) with different polarities of the light emittin…
