Ultraviolet ray measuring method and ultraviolet ray measuring device

An ultraviolet ray measuring device comprising:

• an ultraviolet ray receiving element having a specific spectral sensitivity;
• a storage mechanism storing an estimated value of an entire region estimated from the spectral sensitivity of the ultraviolet ray receiving element and a solar spectral radiation spectrum, and an estimated value of a specific region estimated from a specific action curve and the spectral sensitivity and the solar spectral radiation spectrum;
• and
• a correcting mechanism determining specific ultraviolet ray information by, on the basis of the estimated value of the entire region estimated from the spectral sensitivity of the ultraviolet ray receiving element and the solar spectral radiation spectrum, and the estimated value of the specific region estimated from the specific action curve and the spectral sensitivity and the solar spectral radiation spectrum, correcting an actually measured value which is measured by the ultraviolet ray receiving element.
