A light projection unit is provided that can reduce the production of a portion where the light density is excessively increased on a fluorescent member. This light projection unit includes: a light collection member that includes a light entrance surface and a light emission surface which has an area smaller than that of the light entrance surface; a fluorescent member that includes an application surface to which the laser light emitted from the light collection member is applied and that mainly emits fluorescent light from the application surface; and a light projection member that projects the fluorescent light. The light emission surface of the light collection member is arranged a predetermined distance from the application surface of the fluorescent member.

A light emitting section emits fluorescence upon receiving exciting light emitted from a laser element. The light emitting section includes a plurality of fluorescent material particles made from a single type of fluorescent material or several types of fluorescent materials, the plurality of fluorescent material particles being accumulated on a metal substrate to form a layer of the plurality of fluorescent material particles. Each of the plurality of fluorescent material particles has a surface coated with a coating layer. The coating layer forms an uneven shape of a surface of the light emitting section.
