It is an object of the invention to provide an optical treatment apparatus having a light emitting surface which can properly carry out an optical treatment of the treating apparatus continuously while reducing a temperature of the light emitting surface. There is provided an optical treatment apparatus including surface irradiating means having a plurality of light emitting modules connected in series, and current supplying means for supplying a current to the surface irradiating means. The light emitting module has a light emitting device and an individual current control device which are connected to each other in parallel. The individual current control device is configured to have a greater resistance value than a load impedance of the light emitting device at a predetermined temperature or less and to have a smaller resistance value than the load impedance at a temperature exceeding the predetermined temperature.
