Abstract
A thin-film filter includes thin-film part having a film surface and a rear film surface arranged a rear side of the film surface, a plurality of through holes being formed to penetrate the thin-film part from the film surface to the rear film surface, and stripes-formed inner wall surfaces. The stripes-formed inner wall surfaces include stripe-like parts formed along with an intersecting direction intersecting the film surface. The stripes-formed inner wall surfaces are formed inside the respective through holes.
