<p>PROBLEM TO BE SOLVED: To provide a resin degree-of-curing measuring apparatus for accurately measuring the degree of curing in resin. SOLUTION: When reflection light is divided into two and a wavelength constituent where the change in intensity is smaller to the degree of curing in resin is used as a reference, an external factor simultaneously affects the intensity of both wavelength constituents even if the intensity of a larger wavelength constituent is changed by the external factor such as the temperature change in a target or the like, thus preventing the correlation values from being affected by the external factor other than the degree of curing in resin. An arithmetic unit 10r obtains an output signal according to the intensity of the wavelength constituents after resin coating and before the drive period of a curing-accelerating means, and after resin coating and during a drive period in the curing-accelerating means. Although the correlation values are greatly affected by the degree of curing in resin, it is not affected by other factors easily. As a result, the correlation values accurately change before resin curing and after curing, thus accurately detecting the degree of resin curing.</p> |
