Provided are: a band-pass filter for which filter characteristics can be improved; and a manufacturing method therefor. A band-pass filter, which allows light of a specific wavelength region to pass, includes: a substratewhich has light transmitting properties; a first dielectric multilayer filmthat is provided on a first main surface Sof the substrate; and a second dielectric multilayer filmthat is provided on a second main surface Swhich is opposite the first main surface S. The first dielectric multilayer filmcontains a hydrogenated silicon layer. The second dielectric multilayer filmcontains a hydrogenated silicon layer.

Band-pass filter and manufacturing method therefor

A dielectric multilayer film-incorporated glass plate is disclosed that includes a glass plate and a dielectric multilayer film. The glass plate includes a corner surface located between at least one main surface and a side surface. The dielectric multilayer film includes a main surface covering portion that covers the main surface of the glass plate and a corner surface covering portion that covers the corner surface of the glass plate.
