Abstract
A holder temperature detection method which measures a temperature of a rotatable holder that holds a substrate is provided. The method comprises a step of irradiating a fluorescent body thermally mounted on the holder with a light pulse having a first wavelength, a step of detecting fluorescence having a second wavelength emitted from the fluorescent body due to the light pulse and a step of estimating the temperature of the holder based on the detected fluorescence.
