Abstract

Disclosed is a strip-line filter, which can acquire arbitrary stable filter characteristics while suppressing the external coupling quantity thereof. The strip-line filter comprises an upper-face resonator electrode (13A), an input/output electrode on the lower face of a dielectric substrate (10), and outgoing electrodes connected with the upper-face resonator electrode (13A). The outgoing electrodes include a side-face line portion (14A), an upper-face line portion (16A) and a connecting electrode portion (15A). The side-face line portion (14A) is mounted on the side face of the dielectric substrate (10). The upper-face line portion (16A) is mounted on the upper face of the dielectric substrate (10), and is connected with the upper-face resonator electrode (13A). The connecting electrode portion (15A) is mounted on the upper face of the dielectric substrate (10) with such a line width from the boundary between the side face and the upper face as is different from that of the upper-face line portion (16A), and is connected with the side-face line portion (14A) and the upper-face line portion (16A). The width of the connecting electrode portion (15A) at that boundary is larger than the line width of the side-face line portion (14A).
