    Abstract: An imaging region of an image sensor is used more efficiently. A diffraction element (100) according to the embodiment includes a grating pattern, in which according to a position of light input to the diffraction element, the position being from a center of the diffraction element, an image forming position of diffracted light corresponding to the position of each wavelength is adjusted by adjusting a shape of the grating pattern at the position
