ABSTRACT:
A phosphor layer forming apparatus (1) in which a paste (21) containing a phosphor is discharged so as to cover each of a plurality of light-emitting elements (11) mounted on a substrate (10) includes the following: a discharge portion (12) for discharging the paste (21) in the form of droplets onto each of the light-emitting elements (11); a measurement portion (13) for measuring the thickness of individual phosphor layers that are formed of the paste (21) covering each of the light-emitting elements (11); and a discharge control portion (14) for controlling the amount of the paste (21) to be redischarged for each phosphor layer in accordance with the thickness of the individual phosphor layers measured by the measurement portion (13). This phosphor layer forming apparatus can reduce the manufacturing time.
