Summary:In an LED module, modes to solve such a problem that a loss in the output of light discharged into the atmosphere occurs are embodied. Specifically, in an LED module in which an LED chip is sealed with a sealing resin, a surface of the sealing resin is covered with a thin film, the thin film is made of a material having a smaller linear expansion coefficient than the sealing resin, and an irregular surface is provided on a surface of the thin film such that light from the LED chip is multiply reflected.
