PROBLEM TO BE SOLVED: To provide a resin composition which brings out infrared transparency and biodegradability together, an optical part emitting or sensing infrared light and an electric product equipped with the optical part. SOLUTION: The resin composition comprises mainly polylactic acid, has a light transmittance of≥50% for a wavelength of 900-940 nm and≤40% for a wavelength of 200-700 nm, when measured on a 1mm thick plate prepared from the composition.
