Abstract:
A crystallinity measurement device includes a Raman spectroscopy unit configured to acquire a Raman spectrum of resin-containing material including crystalline thermoplastic resin; and an analysis unit configured to calculate crystallinity of the crystalline thermoplastic resin based on an intensity of a low-wavenumber spectrum that is a spectrum in a region of less than 600 cm−1, in the Raman spectrum.
