The Fabry-Perot interference filter includes: a substrate having a first surface, a first laminate having a first mirror portion disposed on the first surface, a second laminate having a second mirror portion facing the first mirror portion with an air gap interposed therebetween, and an intermediate layer defining the air gap between the first and second laminate. The substrate has an outer edge portion positioned outside an outer edge of the intermediate layer when viewed from a direction perpendicular to the first surface. The second laminate further includes a covering portion covering the intermediate layer and a peripheral edge portion positioned on the first surface in the outer edge portion. The second mirror portion, the covering portion, and the peripheral edge portion are integrally formed so as to be continuous with each other. The peripheral edge portion is thinned along an outer edge of the outer edge portion.
