摘要：
A phosphor according to the present disclosure includes a first crystal phase added with an activator agent, a second crystal phase higher in thermal conductivity than the first crystal phase, and a third crystal phase which is disposed between the first crystal phase and the second crystal phase, and is same in crystal structure as the first crystal phase, and is smaller in additive amount of the activator agent than the first crystal phase.
