Abstract

荧光体轮具备：基板(11)，具有相互背向的第1主面及第2主面；荧光体层(12)，设置于第1主面；及散热部件(30)，由板材构成，与第2主面对置而配置，并且与基板(11)一起旋转；散热部件(30)具有：突出部(34)，以朝向第2主面突出的方式设置在散热部件(30)的中央部，具有与第2主面相接的接触面；及多个鳍片，将除了该中央部以外的周边区域中的多个区域(32)剪切折起而被形成，突出部(34)确保在基板(11)与散热部件(30)之间一定的间隔，并且将基板(11)的热传导到散热部件(30)的周边区域，在多个区域(32)的每一个形成有多个鳍片中的两个鳍片(31A、31B)，两个鳍片(31A、31B)被形成在该区域(32)的沿着散热部件(30)的旋转方向对置的边上。
