PROBLEM TO BE SOLVED: To provide a choke coil and a magnetron capable of obtaining a satisfactory noise suppression function by suppressing the temperature rise of the choke coil.SOLUTION: The inner diameter of a terminal side portion 60 of a core type inductor 50 of a side lead side choke coil 38 is made almost equal to the outer diameter of a magnetic substance core 50b, and the inner diameter of an air-core side portion 61 is made larger than the outer diameter of the magnetic substance core 50b, so that only the periphery of a portion located inside the terminal side portion 60 among portions inserted in the coil 50 of the magnetic substance core 50b is brought into contact with the coil 50, and the periphery of a portion other than that (that is a portion located inside the air core side portion 61) is not brought into contact with the coil 50. Thereby, the temperature of the magnetic substance core 50b hardly rises compared with conventional ones, and reduction of noise suppression function can be suppressed by suppressing a drop in inductance. |
