PROBLEM TO BE SOLVED: To provide a small, simple, and inexpensive ultraviolet receiver, capable of simultaneously separating and precisely and stably measuring ultraviolet rays in different wavelength regions. SOLUTION: This wavelength separation type ultraviolet receiver is provided with at least two ultraviolet receiving elements, formed by successively laminating a semiconductor layer and an electrode on a conductive substrate surface having sensitivity in different wavelength regions. In this case, those ultraviolet receiving elements are laminated in the ultraviolet receiving element.
