Abstract
Provided is, for an industrial magnetron having a large output, a method for manufacturing an industrial magnetron that can be continuously operated by effectively cooling an anode cylindrical body and a magnet and suppressing performance degradation and failure of the anode cylindrical body. The industrial magnetron includes the anode cylindrical body, annular permanent magnets that are arranged above and below the anode cylindrical body to supply a magnetic field, and a cooling block disposed in a columnar shape on the outer circumference of the anode cylindrical body. The cooling block has an anode cylindrical body contact portion, which is a portion in contact with the anode cylindrical body, and a permanent magnet contact portion, which is a portion in contact with the permanent magnets and both the anode cylindrical body and the permanent magnets are cooled by one cooling block.
