PROBLEM TO BE SOLVED: To provide a magnetic device and a frequency detector for industrially utilizing a resonance phenomenon in the direction of magnetization of a magnetoresistance effect element. SOLUTION: The magnetic device comprises: the magnetoresistance effect element 14 having a fixed layer 3, and a free layer 5; a bias magnetic field applying layer 18 for spontaneously generating a static magnetic field 18M2, and applying the static magnetic field 18M2 to the free layer 5; input terminals INPUT1, INPUT2 for supplying an AC signal i to the magnetoresistance effect element 14; and output terminals OUTPUT1, OUTPUT2 for extracting an output voltage from the magnetoresistance effect element 14.
