PROBLEM TO BE SOLVED: To provide an antenna trimmer which has a small number of parts, is easily made light in weight and small in size, and has a small number of elastic connection points and small signal attenuation. SOLUTION: A fold back antenna element 10 is formed by providing strip conductive material having elasticity from a base end side toward a point side, also turning the conductive material back at the point side and forming a tongue piece 10c for elastic connection at the point part. A rod-shaped antenna element 24 is arranged while made to go through an almost cylindrical holding member 12 made of insulation material in an axial direction so as to be able to freely extracted and housed. The antenna element 10 is arranged on the outer circumference of the holding member 12, and a window 12d for looking at the antenna element 24 is pierced in the holding member 14, facing the tongue piece 10c for elastic connection. The tongue piece 10c for elastic connection is brought into elastic contact with the base end part through the window 12d by its own elasticity to be electrically connected while the rod-shaped antenna element 24 is extracted.
