摘要： Disclosed is a plastic product with authenticity to be determined, the plastic product including: a base made of a plastic material, and a luminescent material included in the base and configured to emit light including a second wavelength with respect to incident light including a first wavelength, in which the determination of the authenticity is performed by irradiating the plastic product with the incident light and then detecting the emitted light. According to the present invention, it is possible to easily determine the authenticity of the plastic product by a simple method of detecting a spectrum of the light emitted from the plastic product.
