To decrease the number of parts and to simplify an assembling job for improvement of reliability by forming the resistors in a single body in a high frequency magnetic substance and also on at least one of its both sides.
A magnetic rotor 21 contains center electrodes 12a to 12c buried in a microwave magnetic substance 22. A resistor 14 which is electrically connected a fetch electrode 15 and a coupling electrode 16 is contained in the substance 22 at the part under the electrodes 12a to 12c. A resistor paste layer is baked to the resistor 14 which is led out onto the end face 22a of the substance 22 via the electrode 15. Then a ground electrode 17 is formed under the resistor 14. Thus, the electrodes 12a to 12c serving as the transmission lines, the capacitive electrodes 13a to 13c, the resistor 14, etc., are constructed in a single body in the substance 22.
