A first meander line 1A is formed on one surface of a first dielectric layer 9A, with one end as a signal input position, and the other end connected to a first termination resistance 5A, and a second meander line 1C facing the first meander line 1A is formed on a surface facing the first dielectric layer 9A, and the second meander line 1C is formed, with one end positioned at the other end side of the first meander line 1A as a signal output position, and the other end connected to a second termination resistance 5C, and a first conductor line 3A is formed on the side facing the first dielectric layer 9A, with one end connected to the signal input position and the other connected to the signal output position, and a dividing section in a middle of the first conductor line 3A is connected by a first series resistance 7A.
