PROBLEM TO BE SOLVED: To enhance directivity of an antenna than conventional one.SOLUTION: In an antenna 1, an antenna pattern 20 is formed on a plate-like substrate 10 having such surface as expands in one direction, or length direction, and the other direction, or width direction, among two directions crossing each other. The antenna pattern 20 includes a slit part 23 having an opening 21 looking at one end 11 side in length direction of the substrate 10, a pair of extending parts 25 extending toward one end 11 in length direction of the substrate 10 from two points sandwiching the opening 21 in width direction at the slit part 23, and a protruding part 27 of corrugated structure in which a plurality of projections extending toward a region sandwiched between the pair of extending parts 25 from each of the extending parts 25 are arranged along the length direction. |
