Zusammenfassung:	A light source using a wavelength conversion element is increased in brightness. A wavelength conversion element includes: a wavelength conversion member made of phosphor powder dispersed in a dispersion medium and having a light entrance surface and a light exit surface opposed to each other in a direction of optical axis; and at least two first reflective layers provided inside the wavelength conversion member along a plane parallel to the direction of optical axis and dividing the wavelength conversion member into a plurality of sections.
