1. A multi-band antenna which operates in a plurality of frequency bands, comprising:

  • a feeding point;

    a first conductor which is connected to said feeding point; and

    at least two second conductors which are branched from said first conductor, have a linear shape, and include open ends as ends on a side opposite to said first conductor,wherein the open ends of said second conductors face in substantially the same direction substantially parallel to a side closest to said feeding point out of sides of a region where the antenna is formed,said second conductors include a part at which a distance between said conductors at a portion parallel to the side is a first distance, and another part at which the distance is a second distance shorter than the first distance, andsaid second conductors are electromagnetically coupled at at least the other part,the other parts of each of the last two conductors are arranged on different flat surfaces.
