Abstract: The present invention relates to an optical component and a transparent body used in the optical component. The optical component includes at least one optical element that radiates ultraviolet light, and a package that accommodates the optical element. The package includes a mounting substrate on which the optical element is mounted, and a transparent body that is bonded to the mounting substrate with an organic-based adhesive layer therebetween. The package has a structure in which the ultraviolet light is transmitted through the transparent body but not guided to the adhesive layer, and the ultraviolet light does not directly come into contact with the adhesive layer.
