Abstract: A spectroscope includes a light receiving element and a wavelength selection filter unit. The light receiving element includes a pixel region where a plurality of pixels are disposed. The wavelength selection filter unit is disposed on the pixel region and includes a plurality of wavelength selection filters. The plurality of wavelength selection filters have transmission wavelength characteristics which are different from each other, and split incident light for each wavelength or each wavelength band. The light receiving element generates a light receiving signal by photoelectrically converting light which is split by the wavelength selection filter and is incident on the pixel region, for each pixel.
