    Abstract: A spectrometer includes a support having a bottom wall part and a side wall part surrounding a spectroscopic space, a cover arranged on an opening part formed by the side wall part and provided with a light transmitting part, a joining member arranged between the cover and the opening part, a light detection element supported by the side wall part between the spectroscopic space and the cover, and an optical function part provided on a surface of the bottom wall part. A vent is provided in at least one of the support, the cover, and the joining member. The vent is open to an outside and a space defined by the support, the cover, and the light detection element. The space communicates with the spectroscopic space.

    Abstract: A spectrometer 1A includes a package 2 having a stem 4 and a cap 5, an optical unit 10A disposed on the stem 4, and a lead pin 3 for securing the optical unit 10A to the stem 4. The optical unit 10A includes a dispersive part 21 for dispersing and reflecting light entering from a light entrance part 6 of the cap 5, a light detection element 30 having a light detection part 31 for detecting the light dispersed and reflected by the dispersive part 21, a support 40 for supporting the light detection element 30 such that a space is formed between the dispersive part 21 and the light detection element 30, and a projection 11 protruding from the support 40, the lead pin 3 being secured to the projection 11. The optical unit 10A is movable with respect to the stem 4 in a contact part of the optical unit 10A and the stem 4.
