    摘要: A light source device includes: a light-emitting section including plural light-emitting elements; a shifter that performs a shift operation; and a controller that causes the shifter to perform the shift operation to set, among the plural light-emitting elements, a light-emitting element which is to emit light, that changes the shifter to an OFF state after the set light-emitting element is shifted to a state in which the set light-emitting element is able to emit light, and that causes the set light-emitting element to emit light multiple times by turning ON and OFF a voltage application side of a power source, the power source supplying a light-emitting current which causes the light-emitting element to emit light.

    摘要: A method for manufacturing a laminated substrate includes removing a portion not covered with a resist layer (256) from a laminated substrate with an etchant to form a wiring (261), the laminated substrate including: a base layer including a mesa portion having a trapezoidal cross section, the mesa portion having a first inclined surface (252) extending downward and outward from a top surface and a second inclined surface (253) having an eaves-shaped portion (253a, along line 253b) protruding outward from the top surface; a wiring layer (254) formed on an upper surface of the base layer; and the resist layer (256) formed on an upper surface of the wiring layer and having a shape corresponding to a shape of the wiring (261), and the wiring is arranged at a position where the wiring covers a whole of the eaves-shaped portion (253a, along line 253b) of the second inclined surface.
