Abstract: A spectrometer includes a support having a bottom wall part in which a depression is provided and a side wall part, a light detection element supported by the side wall part while opposing the depression, a resin layer disposed at least on an inner surface of the depression, and a dispersive part provided in the resin layer on the inner surface of the depression. The resin layer is in contact with an inner surface of the side wall part. A thickness of the resin layer in a first direction in which the depression and the light detection element oppose each other is larger in a part in contact with the inner surface of the side wall part than in a part disposed on the inner surface of the depression.

Abstract: An optical element includes a base having a curved depression formed in a front surface thereof and a formed layer arranged on the base. The formed layer includes a main part in the depression as viewed from a depth direction of the depression and an overhang on the front surface of the base while connecting to the main part. An opposite surface of the main part to a surface thereof on a side of an inner surface of the depression is formed like a concave curve that is concave in a same direction as the inner surface of the depression. A predetermined surface of the main part that is opposed to the inner surface of the depression is provided with an optical function part.
