ルタ。 In a bandpass filter in which a tuned circuit consisting of a coil, a resonant line, and a capacitor is inductively coupled in three or more stages, the resonant line of at least one tuned circuit is formed by connecting two conductors that are easily plastically deformed in parallel. What is claimed is: 1. A bandpass filter, characterized in that the bandpass filter is configured to adjust the degree of mutual inductive coupling with an adjacent tuned circuit by deforming the conductor.
