Provided are: a band-pass filter for which filter characteristics can be improved; and a manufacturing method therefor. A band-pass filter 11, which allows light of a specific wavelength region to pass, includes: a substrate 12 which has light transmitting properties; a first dielectric multilayer film 13 that is provided on a first main surface S1 of the substrate 12; and a second dielectric multilayer film 14 that is provided on a second main surface S2 which is opposite the first main surface S1. The first dielectric multilayer film 13 contains a hydrogenated silicon layer. The second dielectric multilayer film 14 contains a hydrogenated silicon layer.
