PROBLEM TO BE SOLVED: To provide an element antenna, with which the occurrence of gain fluctuations on a high-frequency band is reduced, in the element antenna having wide band characteristics. SOLUTION: In the element antenna, with which the apexes of two plate-like conductors in the form of isosceles triangle are made to confront in the same plane and a feeding point is provided on the gap thereof, the angle characteristics of radiated power are reduced over a wide band by a band-like conductor connected, so as to be folded to the terminal part of the plate-like conductor orthogonal in the lengthwise direction of the element antenna and the total equilateral length becomes almost quarter of the wavelength of a first frequency and further, its own length becomes almost the quarter of the wavelength of a second frequency.
