Colorimetric measurement method, colorimetric measurement device and manufacturing method of wavelength conversion component

Abstract

In this invention, a light-emitting portion 4 for emitting light L is disposed on the adhesive sheet 7 side of a laminate 10 formed by stacking and attaching an adhesive sheet 7 to a wavelength conversion member 2 containing a phosphor, and a light-receiving portion 5 for receiving light L is disposed on the wavelength conversion member 2 side of the laminate 10. In this state, light L is irradiated onto the laminate 10 from the light-emitting portion 4, and the chromaticity of the wavelength conversion member 2 is measured based on the light L received from the laminate 10 by the light-receiving portion 5. At this time, the front end of the light-emitting portion 4 is brought into contact with the adhesive sheet 7 at a position corresponding to the wavelength conversion member 2.
