摘要：
A voltage is applied on a first branch 3a by a first ground electrode 10 and a signal electrode 11, and a voltage is applied on a second branch 3b by a second ground electrode 12A and the signal electrode 11. A first gap 13 is formed between the first ground electrode 10 and the signal electrode 11, and a second gap 14 is formed between the second ground electrode 12A and the signal electrode 11. The first gap 13 and the second gap 14 are divided into voltage applying portions 13a, 14a, feed-through portions and connection portions 13b, 14b therebetween, respectively, and satisfy the formula: G12/G11≦G22/G21
