PROBLEM TO BE SOLVED: To provide a dBm linear high-frequency power detector requiring no calibration and no external temperature compensation, having simple circuit constitution compared with a dBm linear power detector by a well-known technique, i.e. having the circuit constitution of no active constitutive element, of which the passive constitutive elements are reduced to a very small number. SOLUTION: In this high-frequency power detector, high-frequency electric vibration is input-coupled to a circuit part having the first diode by a coupling means, a signal having a direct current component depending on electric power of the high-frequency electric vibration is formed in a connection point, and the connection point is connected to a series circuit comprising the second diode and a resistance, and a means for leading out a voltage to the second diode.
