PROBLEM TO BE SOLVED: To provide an antenna having a structure suitable for protecting a power feeding unit from waterdrops sucg as rain. SOLUTION: The antenna 1 includes radiation conductors 2, 3, a lead wire part 4 and a power feeding terminal 5. All the radiation conductors 2, 3 and the lead wire part 4 are conductors in a thin plate shape and they are integrated. The radiation conductor 2 is formed linear. The radiation conductor 3 is formed rectangular, and its length in a width direction is greater than a line width of the radiation conductor 2. The radiation conductor 3 further includes a slot part 6 wherein an elongated hole is formed. The lead wire part 4 is formed linear similarly to the radiation conductor and its one-side end is connected to the radiation conductor 3. The power feeding terminal 5 is connected to the radiation conductor 2 and has a shape protruding in a direction crossing a surface of the radiation conductor 2. Since there is only one power feeding terminal in the antenna 1, the power feeding terminal can be made waterproof in simple configuration. COPYRIGHT: (C)2010,JPO&INPIT
