Substrate for light emitting device and manufacturing method of substrate for light emitting device
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.
