Claim 14:
15. A method of producing a light emitting device, the method comprising the steps of:
providing a substrate, the substrate including:
a base member containing a resin material and having a top surface,
a first wiring portion, a second wiring portion, a third wiring portion and a fourth wiring portion that are located on the top surface of the base member, and arrayed in a first direction; and
a connection wiring portion connecting the second wiring portion and the third wiring portion to each other, the connection wiring portion including:
a first connection end connected with the second wiring portion,
a second connection end connected with the third wiring portion; and
a connection central portion connecting the first connection end and the second connection end to each other, the connection central portion having a maximum width in a second direction perpendicular to the first direction that is different from each of a maximum width of the first connection end and a maximum width of the second connection end, and the connection wiring portion including a portion that is narrower than each of a maximum width of the second wiring portion and a maximum width of the third wiring portion in the second direction;

placing a first light emitting element on the first wiring portion and the second wiring portion using the connection wiring portion as a reference;
placing a second light emitting element on the third wiring portion and the fourth wiring portion using the connection wiring portion as a reference;
forming a cover member covering the top surface of the base member, a lateral surface of the first light emitting element and a lateral surface of the second light emitting element,
wherein providing the substrate includes forming a gold plating layer at an outermost surface of each of the first wiring portion, the second wiring portion, the third wiring portion, the fourth wiring portion and the connection wiring portion by electrolytic plating.
