PROBLEM TO BE SOLVED: To provide a high frequency circuit component for configuring a microwave irreversible circuit element such as a circulator and an isolator in which a center conductor has a low resistance to decrease the insertion loss. SOLUTION: In the high frequency circuit component 1 that is provided with center conductors 3-5, and with a microwave magnetic material 2 into which the center conductors 3-5 are imbedded and where the center conductors 3-5 and the magnetic material 2 are integrally sintered and a permanent magnet applies a DC magnetic field to the center conductors 3-5 and the microwave magnetic material 2, the center conductors 3-5 adopt a material of a gold single body or a material consisting of a gold as a major component, 15.0 atom.% of rhodium or less, 5.0 atom.% of palladium or less, and/or 5.0 atom.% of platinum or less.
