Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a spectral sensor having a high reliability.

SOLUTION: A spectral sensor 1 comprises: an interference filter part 20 having a cavity layer 21 and first and second mirror layers 22, 23 facing each other via the cavity layer 21 and selectively transmitting light in a predetermined wavelength range according to an incident position; a light transmission substrate 3 being arranged on the side of the first mirror layer 22 and transmitting light incident to the interference filter part 20; and a light detection substrate 4 being arranged on the side of the second mirror layer 23 and detecting light having transmitted through the interference filter part 20. The cavity layer 21 includes: a filter region 24 sandwiched between the first and second mirror layers 22, 23; an annular enclosure region 25 enclosing the filter region 24 at a predetermined distance from the filter region 24; and an annular connection region 26 connecting an end part 24e, on the side of the light detection substrate 4, of the filter region 24 and an end part 25e, on the side of the light detection substrate 4, of the enclosure region 25.
