摘要：
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.
