本发明之萤光体树脂片之制造方法依序包括：步骤(1)，其系准备B阶段之萤光体树脂片；步骤(2)，其系于萤光体树脂片形成贯通孔及面向贯通孔之贯通面；及步骤(3)，其系将萤光体树脂片切断而形成包含贯通面之复数个萤光体树脂片。于步骤(3)中，以切断线通过贯通孔之方式将萤光体树脂片切断，借此，以划分1个贯通孔之贯通面被分配至复数个萤光体树脂片之各者之方式将贯通面分割，而获得具有自周端面向内侧切除之缺口部之复数个萤光体树脂片。

This method for producing a fluorescent resin sheet includes, in order, a step (1) for preparing a B-stage fluorescent resin sheet, a step (2) for forming through-holes in the fluorescent resin sheet and through-planes therein that run into the through-holes, and a step (3) for forming a plurality of fluorescent resin sheets that contain through-planes by cutting up the fluorescent resin sheet. During the step (3), a plurality of fluorescent resin sheets that have notches that are notched to the inside from the peripheral end surfaces thereof are obtained by cutting up the fluorescent resin sheet in a manner such that the cutting lines pass through the through-holes, and as a result, the through-planes are divided in a manner such that the through-planes for demarcating one through-hole are allocated to each of the plurality of fluorescent resin sheets.
