PURPOSE: A magnetron for electronic range is provided to enhance reliability and lengthen life. CONSTITUTION: The present invention discloses a magnetron for electronic range comprising: an A seal(101) sustaining the seal feature of a magnetron and forming a passage for a magnetic circuit; an A ceramic(104) attached to the top of the A seal and consisted of ceramic insulator; a bent part(102) formed by bending downwardly the opening of the A seal and serving as a choke; and a continuous circumferential protrude(103) formed on the bent part. The section of the protrude has triangular shape for minimizing the contact area with the A ceramic. Therefore, the present invention can enhance reliability and lengthen life.
