Abstract
A resin composition quality controlling method includes a step of measuring a Raman spectrum of a resin composition composed of first TiOparticles of anatase type TiOand second TiOparticles of rutile type TiOby irradiation with laser, and determining a concentration ratio of the first TiOparticles to the second TiOparticles in the resin composition based on an intensity of a first peak assigned to lattice vibration in the anatase type TiOand an intensity of a second peak assigned to lattice vibration in the rutile type TiOin the Raman spectrum.
