PROBLEM TO BE SOLVED: To provide an antenna element whose winding pitch is not changed and the electric characteristic of which is hardly changed even when the antenna element is bent. SOLUTION: A helical coil 10a with elasticity is inserted to a support member 11 a helical groove 11a of which is formed to an outer circumferential face. Thus, even when the antenna element 2 is bent, the winding pitch of a helical element 10 is unchanged and the electric characteristic of the antenna element 2 is stabilized.
