A power transmission-side measuring jig (101A) is disposed with respect to a power transmission apparatus (101) that applies an alternating current voltage to an active electrode (11) and a passive electrode (12), said alternating current voltage having been boosted by means of a booster transformer (T1). The power transmission-side measuring jig (101A) has a measuring active electrode (11A) facing the active electrode (11), and a measuring passive electrode (12A) facing the passive electrode (12), and the measuring active electrode (11A) and the measuring passive electrode (12A) are short-circuited to each other. In a state wherein the power transmission-side measuring jig (101A) is disposed with respect to the power transmission apparatus (101), frequency characteristics of a series resonant circuit formed by means of leakage inductance of the booster transformer (T1) and capacitors (Ca, Ca1, Cp1) are measured. Consequently, a frequency characteristic measuring method, whereby frequency characteristics of each of a power transmission apparatus and a power reception apparatus of a wireless power transmission system can be independently measured, is provided. |
