A second conductor plane (102) is formed in a layer different from a layer in which a first conductor plane (101) is formed, and faces the first conductor plane (101). A first transmission line (104) is formed in a layer different from the layers in which the first conductor plane (101) and the second conductor plane (102) are formed, and faces the second conductor plane (102), and one end thereof is an open end. A conductor via (106) connects the other end of the first transmission line (104) and the first conductor plane (101). An insular conductor (112) is connected to a portion of the first transmission line (104) other than a portion thereof at which the transmission line (104) is attached to the conductor via (106), is located in a layer different from the layer in which the second conductor plane (102) is located, and faces the second conductor plane (102). |
