An electrode pattern (13) formed on a ceramics layer (2) in a substrate for a light emitting device (circuit board (320)) of the present invention includes a first metal layer (5), a second metal layer (7), and an electrode terminal unit (10), and the thickness of a part at which the electrode terminal unit (10) is not formed in the electrode pattern (13) is at least equal to or greater than 35 μm. Accordingly, it is possible to suppress heat resistance to be low.
摘要:
A ceramic insulating film (150) having a heat conducting property and a light reflecting property is formed on a front surface of a substrate (100), and a light emitting element (110) is provided on the ceramic insulating film. This makes it possible to improve a heat dissipation characteristic and a light utilization efficiency of a light emitting apparatus (10) having the light emitting element (101) provided on the substrate (110).
