This power sensor has a magnetic element that has a magnetic film, which is patterned in an oblique direction at a conductor, a first element terminal, which is connected to one end of the conductor, and a second element terminal, which is connected to the other end of the conductor, and during measurement, the first element terminal is connected to the subject device that is the subject of power measurement. The power sensor has: a measurement resistor of which one end is connected to the second element terminal of the magnetic element; and a detector that detects the DC component of the voltage between the first element terminal and the second element terminal. The magnetic element is disposed in a manner such that the direction from the first element terminal to the second element terminal during measurement is approximately parallel to the wire connected to the subject device. |
