PROBLEM TO BE SOLVED: To make the output control of the microwave application device easily and correctly by preventing appearance of two wave crests in the occupied bandwidth. SOLUTION: In the installation of the positive electrode member 2 which is installed on the inner wall of the positive electrode cylinder 1, the positive electrode member 2 is installed so that the center of the positive electrode member 2 in the direction crossing the center axis Z-Z of the positive electrode cylinder 1 in the right angles is positioned eccentric to the center of a straight line made by connecting the top end edge of the output portion of the positive electrode cylinder 1 (on the side of installation of the antenna lead 5) and the top end edge of the input portion (on the side of taking out the feeding lead of the negative electrode structure 7).
