Abstract: A common mode noise filter includes: a plurality of insulator layers; and a first coil conductor, a second coil conductor, a third coil conductor, a fourth coil conductor, a fifth coil conductor, and a sixth coil conductor. A first interval I1 measured in an upward/downward direction from an upper surface of the first coil conductor to a lower surface of the third coil conductor, a second interval I2 measured in the upward/downward direction from an upper surface of the fourth coil conductor to a lower surface of the sixth coil conductor, and a third interval I3 measured in the upward/downward direction from the lower surface of the third coil conductor to the upper surface of the fourth coil conductor satisfy I1

Abstract: High frequency heating device is provided with heater disposed adjacent to mount base on which object to be heated is mounted and having a plurality of surface wave transmission lines electrically isolated from each other, and first and second high frequency power generators, each of which generates high frequency power having different frequency. Surface wave transmission lines receive at least one of the high frequency power generated by first high frequency power generator and the high frequency power generated by second high frequency power generator. According to this aspect, interference between the high frequency powers is not occurred and electromagnetic field coupling is not occurred. As a result, in the high frequency heating device provided with the surface wave transmission line using a periodic structure, uneven baking caused by the electromagnetic field coupling can be suppressed, and a heating state of an object to be heated can be easily controlled.
