According to an exemplary embodiment, a lighting apparatus includes a light source (20, 62, 40) that includes a light emitting element (30, 42), and a member (14, 16, 64) which is irradiated with light emitted from the light source (20, 62, 40) and which is formed of resin having absorptivity of 15% or less in a wavelength in which intensity is 10% of a peak intensity, at a wavelength side that is shorter than an intensity peak of a spectrum of blue light emitted from the light source (20, 62, 40).
