PROBLEM TO BE SOLVED: To complete antenna matching in a short time and enable a quick judgement about impossible matching when matching is impossible. SOLUTION: An antenna matching device 1 is provided with an impedance matching means, a frequency information acquisition means which acquires transmission frequency information, an impedance matching status detection means which detects impedance matching status, an antenna property information storage means which memorizes the property information of an antenna 8, and a matching element control means which controls values of necessary elements of the impedance matching means based on signals from the antenna property information storage means, the frequency acquisition means and the impedance matching status detection means.
