To suppress unevenness in intensity distribution of output light in a longitudinal direction of a light guide body, a lighting apparatus includes a rod-shaped light guide body, and light source units provided in end faces of the body, where the light guide body includes first and second reflecting surfaces that perform diffuse reflection on light input from the light source, and a light output surface that outputs reflected light from both of the reflecting surfaces to the outside. The first reflecting surface includes a first diffuse reflection pattern having discontinuous pattern portions provided near the end faces in the longitudinal direction of the light guide body and a continuous pattern portion in the center portion, and the second reflecting surface includes a second diffuse reflection pattern to reduce a ripple in the longitudinal direction of a quantity of the light reflected from the first diffuse reflection pattern and output.
