Abstract
A distributed constant type filter includes a substrate including a part made of a first dielectric material having a first relative dielectric constant and a different-material part made of a second dielectric material having a second relative dielectric constant different from the first relative dielectric constant. A filter pattern is formed on a top surface and a ground pattern is formed on a bottom surface of the substrate. Part of the filter pattern is formed on the different-material part.
