PROBLEM TO BE SOLVED: To efficiently emit light emitted from a light emitting element to the outside of the substrate for mounting a light emitting element mainly composed of at least one selected from gallium nitride, indium nitride, and aluminum nitride And a substrate capable of controlling the direction of light emission emitted to the outside of the substrate. SOLUTION: A sintered body mainly composed of a light-transmitting ceramic material, or an antireflection member, or a sintered body mainly composed of a ceramic material on which a reflecting member is formed is used as a light-emitting element mounting substrate. Thus, it is possible to efficiently emit light emitted from the light emitting element mounted on the substrate to the outside of the substrate and control the direction of light emitted to the outside of the substrate. Further, the light emitted from the light emitting element that is transmitted through the substrate and emitted to the outside of the substrate is likely to be scattered light, so that it becomes a gentle and easy light source for human eyes.
