Abstract (en)

[origin: EP2237304A2] Unnecessary noises generated from a magnetron for a microwave oven are suppressed. In a magnetron 10 for a microwave oven, the diameter IP1 of the through-hole 33 of the input side pole piece 31 is 8.6 to 9.1 mm and the outer diameter IP2 of the internal surface 41 of the input side pole piece 31 is 15 to 16 mm, while the diameter OP1 of the through-hole 34 of the output side pole piece 32 is 7.9 to 8.1 mm and the outer diameter OP2 of the internal surface 42 of the output side pole piece 32 is 11 to 13 mm. Additionally, the interval distance D1 between the outer annular portion 35 of the input side pole piece 31 and the outer annular portion 36 of the output side pole piece 32 is 11.5 to 13.5 mm and the interval distance D2 between the inner annular portion 39 of the input side pole piece 31 and the inner annular portion 40 of the output side pole piece 32 is 10.2 to 11.2 mm.
