Claim 10:
11. A lamp device, comprising:
a wiring substrate;
a first bus electrode formed on the wiring substrate along one direction;
a plurality of first electrode lines each formed on the wiring substrate, and extending from the first bus electrode;
a plurality of semiconductor light-emitting devices disposed to be parallel to one another along a direction in which the plurality of first electrode lines are formed and spaced apart from the plurality of first electrode lines by a predetermined distance;
a current injection part formed along the one direction to be disposed parallel to the first bus electrode; and
