Zusammenfassung:PROBLEM TO BE SOLVED: To provide an antenna of a reduced size.SOLUTION: A first SRR pattern 21 to a fourth SRR pattern 24 in four layers are formed between surfaces and rear faces of isolation layers 11 to 13 which form three layers, and the four layers are connected by via connection. The SRR patterns 21 to 24 in the respective layers form an antenna with: a broken annular part 26 in a rectangle shape with a broken part formed therein; a sprit part 27 having a first sprit part 27a continuous with one end of the broken part of the broken annular part 26 and extending toward an inner side; a second sprit part 27b continuous with another end and formed parallel to the first sprit part 27a at a prescribed distance therefrom; and a feed line connected to the broken annular part 26 in a third layer. The broken part of the broken annular part 26 is formed at a corner of the broken annular part 26 in the rectangle shape so that the antenna can be made small in size.
