Abstract
A spectrometer includes a support having a bottom wall part in which a depression including a concave curved inner surface and a peripheral part adjacent to the depression are provided, and a side wall part disposed on a side on which the depression is open with respect to the bottom wall part, a light detection element supported by the side wall part while opposing the depression, and a dispersive part disposed on the inner surface of the depression. A length of the depression in a second direction in which a plurality of grating grooves included in the dispersive part is aligned is larger than a length of the depression in a third direction orthogonal to the second direction when viewed in a first direction in which the depression and the light detection element oppose each other. An area of the peripheral part adjacent to the depression in the second direction is larger than an area of the peripheral part adjacent to the depression in the third direction when viewed in the first direction.
