摘要：
A fluorescent material-containing sealing resin (20) production method of the present invention includes: a kneading step of kneading a powder mixture (24), which has been obtained by mixing a powder of silicone resins (21) and a powder of fluorescent materials (22) together, while melting the powder mixture (24) by heat, so that a kneaded mixture (25) is obtained; and an extruding step of extruding the kneaded mixture (25) in a form of a cord from an output port (37b) of a twin screw extruder (37).
