Provided is a photodynamic therapy device, comprising: a light source (2), further comprising a plurality of LEDs (4); a photodetector (3) which detects, as a light intensity distribution of the light which the light source (2) emits, the intensity of the light which each of the plurality of LEDs (4) emits; and a light intensity distribution control circuit (6) which controls a current which drives each of the plurality of LEDs (4) such that the intensity of the light which each of the plurality of LEDs (4) emits which is detected by the photodetector (3) falls within a prescribed range. |
