A light source circuit unit and a lighting device including the light source circuit unit that are configured such that a bent-type metal substrate is formed on an upper surface of the printed circuit board so that the occurrence of a defect due to circuit damage at a bent part upon bending the substrate can be prevented, and slimness and a heat-dissipation property of a device can be improved. The light source circuit board includes: a substrate having a first part with at least one opening portion, and a second part bent from the first part; a printed circuit board on one surface of the substrate; and a light source element mounted to the printed circuit board and inserted into the opening portion, the light source element emitting light to an opposing side of the substrate.
