PROBLEM TO BE SOLVED: To provide a light source for illumination capable of irradiating illumination light for a minority of color vision in which a decrease in the amount of light is suppressed. An illumination light source 11 that irradiates an illumination light L1 for a minority of color vision includes a blue light emitting unit that emits blue light L1b and a red light emitting unit that emits red light L1r. The spectrum of the illumination light L1 for the color vision minority including the blue light L1b and the red light L1r has a minimum value in the wavelength band of 440 nm or more and 600 nm or less in the range of 535 nm ± 50 nm, and a maximum value in the wavelength band. , 485 nm or less, or 585 nm or more.
