Abstract
A resin composition quality controlling method includes a step of measuring a Raman spectrum of a resin composition composed of TiOparticles dispersed in a base material mainly composed of a silicone rubber by irradiating the resin composition with laser, and a step of determining a concentration of the TiOparticles in the resin composition based on an intensity of a fluorescence spectrum in the Raman spectrum.
