Abstract: A Fabry-Perot interference filter includes: a substrate having a first surface and a second surface facing each other; a first layer structure disposed on the first surface; and a second layer structure disposed on the second surface, wherein the first layer structure is provided with a first mirror portion and a second mirror portion facing each other with an air gap therebetween, and a distance between the first mirror portion and the second mirror portion is varied, and the second layer structure is formed with a separation region separating at least a part of the second layer structure into one side and another side in a direction along the second surface.

Abstract: A light detection device includes: a Fabry-Perot interference filter provided with a light transmission region; a light detector configured to detect light transmitted through the light transmission region; a package having an opening and accommodating the Fabry-Perot interference filter and the light detector; and a light transmitting unit arranged on an inner surface of the package so as to close an opening, the light transmitting unit including a band pass filter configured to transmit light incident on the light transmission region. When viewed from a direction parallel to the line, an outer edge of the Fabry-Perot interference filter is positioned outside an outer edge of the opening, and an outer edge of the light transmitting unit is positioned outside the outer edge of the Fabry-Perot interference filter.
