PROBLEM TO BE SOLVED: To provide an antenna that is hard to resonate.SOLUTION: An antenna 3 includes three legs 11 to 13 extending perpendicular to a substrate 2 and a rectangular annular arm part 20 supported by each of the legs 11 to 13. The arm part 20 is composed of four arms 21 to 24. A plate thickness direction of the leg 11 and the leg 13 as well as the arm 21 and the arm 23 is made to be a front and back direction. A plate thickness direction of the arm 22 and the arm 24 is made to be an up and down direction. A plate thickness direction of the leg 12 is made to be a right and left direction. |
