An illuminating apparatus includes: a light source that emits a source light; and a light guiding module that has an overlap rod portion which can pass luminous fluxes traveling in different directions therethrough and has a returning member which returns the luminous fluxes having passed through the overlap rod portion at least once so that the luminous fluxes enter the overlap rod portion in directions different from the previous time, whereby the source light is made uniform.
