A light source that emits light, wherein, in coordinates in a CIE 1931 chromaticity diagram, the light has a color purity included in a region of 2 to 50 in a region surrounded by a line segment WB and a line segment WG that connect coordinates W (0.33, 0.33) indicating an achromatic color with coordinates B (0.091, 0.133) of 480 nm and coordinates G (0.373, 0.624) of 560 nm on a spectral locus, and the spectral locus, and has an area occupied by a continuous spectral wavelength in a wavelength region of 480 to 540 nm, of 15% or more relative to an area of an overall spectral wavelength of the light source at 380 to 780 nm.
