PROBLEM TO BE SOLVED: To provide a light emitting unit which enables simplification of the structure to achieve low costs and effectively prevents deviation of the light distribution caused by heat deformation of a member forming the light emitting unit to prevent deterioration of the light radiation efficiency.SOLUTION: A light emitting unit includes: a case part 1 extending in one direction; a substrate 2 disposed in the case part 1 and extending in an extension direction of the case part 1; one or more light emitting elements 3 mounted on the substrate 2; and inner sheet materials 3 disposed in the case part 1 and extending in the extension direction of the case part 1. Each inner sheet material 4 is divided into a reflection part 5, which is disposed above the substrate 2 so as to be separated from the substrate 2 and reflects light radiated from the light emitting element 3, and a translucent part 6, which is disposed so as to transmit the light reflected by the reflection part 5. |
