1. A light-emitting device comprising:
a wiring substrate;
a base member provided on the wiring substrate;
a light-emitting element array that has a first side surface and a second side surface facing each other, that has a third side surface and a fourth side surface facing each other and connecting the first side surface and the second side surface, and that is provided on the base member;
a drive unit that is provided on the wiring substrate at a side of the first side surface and drives the light-emitting element array;
a first circuit element that is provided on the base member at the side of the first side surface;
a second circuit element that is provided on the base member at a side of the second side surface and has a larger occupation area on the base member than the first circuit element; and
wiring members that are provided at a side of the third side surface and at a side of the fourth side surface and extend from an upper surface electrode of the light-emitting element array toward an outer side of the light-emitting element array.
