Abstract
A crosslinked fluoropolymer resin is configured to include a measuring step of irradiating a surface of the crosslinked fluoropolymer resin with a laser to measure a Raman spectrum, and an acceptance or rejection decision step of determining an acceptance or a rejection of a quality of a measurement region irradiated with the laser, on the basis of an intensity of a fluorescence spectrum relative to an intensity of a Raman scattering peak, which is ascribed to a CFstretching vibration, in the measured Raman spectrum.
