Abstract
The colorimetry apparatus includes a light source for emitting light to a surface of a detected object, a diffraction grating for spectrally separating, for each wavelength, the light emitted from the light source and reflected by the detected object, and a line sensor including multiple pixels, for receiving the light, which is spectrally separated by the diffraction grating, for the each wavelength by the multiple pixels. The light source and the line sensor are arranged on the common substrate.

1-11. (canceled)
A colorimetry apparatus comprising:
- a light emission device configured to emit light to a surface of a detected material;
- a diffraction grating configured to spectrally separate light by wavelengths, the light having been emitted from the light emission device and reflected by the detected material;
- and
- a light receiving device including multiple pixels, configured to receive spectral light for each of the wavelengths by the multiple pixels, the spectral light having been spectrally separated by the diffraction grating;
- a substrate including a common surface on which the light emission device and the light receiving device are provided;
- and
- a housing that is a different member from the substrate,
- wherein the light emission device, the diffraction grating, the light receiving device, and the substrate are provided inside the housing.
