To provide non-coloring excellent white color by combining plural light emitting bodies having different light emitting wavelengths in a surface light source device.

LED chips 18R, 18G, 18B whose light emitting colors are red, green, and blue are closely arranged on a circuit board 15, and are sealed by transparent resin 19 so as to form a light emitting body group 16. The respective LED chips 18R, 18G, 18B of the light emitting group 16 radiate red light, green light, and blue light from close positions, the radiated red color, the green color, and the blue color are reflected, deflected on a boundary face, and mixed so as to be radiated from the light emitting group 16 as white light to a light guide plate 12.
