摘要： A thermoplastic resin composition that cuts visible light and has infrared light transmittance. A thermoplastic resin composition including a thermoplastic resin and a coloring material, wherein the refractive index at a wavelength of 894 nm is 1.60 or greater, and when the thickness of the thermoplastic resin composition is 1 mm, the maximum value of the transmittance of wavelengths of 380 nm-630 nm is greater than 0% and less than or equal to 1.00%, and the average transmittance of wavelengths of 840 nm-940 nm is greater than or equal to 80%.
