Provided is a lighting apparatus which provides an excellent heat dissipation effect, and has high output and a large light emitting area. Provided are: a housing 7 having a rectangular cylindrical shape obtained by forming a belt-like body 12 including a plurality of holding bodies 1 in a rectangular cylindrical shape and further connecting end portions of a belt-like body 12 formed in the rectangular cylindrical shape; and a circuit board 2 mounted on an inner surface of the housing 7 and further including a light source 3. The circuit board 2 includes: a mounting portion 2a mounted on the inner surface of the housing 7 and having a surface provided with the light source 3; and a connecting portion 2b which connects the mounting portions 2a, 2a adjacent to each other in a peripheral direction of the housing 7 and is bendable at a corner of adjacent inner surfaces of the housing 7, and a rear surface of the mounting portion 2a contacts an inner surface (mounting surface 5a) of the holding body 1. Therefore, it is possible to provide a lighting apparatus which provides an excellent heat dissipation effect and has high output and a large light emitting area. |
