The mounting members of the lighting devices of Patent Document 1 and Patent Document 2 are required to have rigidity in a state where the LED substrate, the cover member, the power supply device, and the like are arranged. The mounting member is formed in a long and rectangular plate shape and has a bottom surface on which the LED substrate is mounted on one surface, and a direction in which both ends in the width direction of the bottom surface are opposite to the LED substrate and intersect with the bottom surface. It is formed of a first side surface portion and a second side surface portion that project to the LED. Therefore, the mounting member has a complicated shape and is a factor that hinders the weight reduction of the light source unit.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a light source unit and a lighting device in which a mounting member to which an LED substrate is mounted has a simple shape and rigidity can be obtained. It is a thing.

The light source unit according to the present invention includes a light emitting portion arranging portion in which a light emitting portion is arranged on a first surface, a flat plate-shaped frame member having a component arranging portion on a second surface behind the first surface, and the component arrangement. A case member to be attached to the portion is provided, and an attachment component for attaching the frame member to the instrument main body is arranged in the component arrangement portion, and the frame member is the second along the longitudinal direction of the frame member. The case member has a protruding portion projecting to the surface side, and the case member is provided with a first recess opened to the side where the frame member is arranged and the first recess adjacent to the first recess. A second recess that is open toward the side opposite to the opening direction and a side wall portion that separates the first recess and the second recess are provided, and the side wall portion is connected to the protrusion.
