1. A power transmission device comprising:
a first resonance element; a power generation section configured to generate power supplied to said first resonance element; a variable matching section having an impedance matching function configured to match the impedance at a power supplying point of said first resonance element in accordance with a control signal; a detection section configured to detect a state of power transmission; and a first control section configured to receive a result of the detection of said detection section and output the control signal to said variable matching section so as to raise a power transmission efficiency by impedance matching by said variable matching section based on the received result of the detection.
