Abstract
It is an object to provide a magnetron for a small-sized microwave oven which takes safety standards and a noise into consideration, in a magnetronfor a microwave oven, a pair of choke coilsandare provided in a filter case, and a height Hof the internal surface of the filter caseis set to be 35 to 45 mm, an outside diameter dof an air-core type inductanceis set to be 5.5 to 7.5 mm and a sectional area S of a high frequency absorbing memberis set to be 5 to 16 mm. In the magnetronfor a microwave oven, an electrostatic capacity between capacitor terminalsA andB and the filter caseis increased to be 500 to 700 pF.
