ABSTRACT:
The light irradiation device is provided that can reduce moire interference with a simple and low-cost arrangement without sacrificing a compact design by comprising a transparent plate31which has a predetermined thickness and one of whose surfaces is arranged as an object facing surface31ato face an object W such as a product on which light is to be irradiated, multiple reflecting sections32that are laid out on other surface of the transparent plate31with forming a microscopic space S therebetween with its light reflecting surface facing a direction of the object W, a light source section5arranged at a position where at least a part of the emitted light is transmitted, reaches the light reflecting surface, is reflected on the light reflecting surface and is emitted from the object facing surface31a, and an antireflection film33that covers the object facing surface31a.
