1. A power transmission apparatus that supplies power to a power reception apparatus without contact therebetween, the power transmission apparatus comprising:
a power conversion unit that outputs an alternating-current voltage of a predetermined frequency;
a power transmission unit that has a power transmission coil and a capacitor that is connected to the power transmission coil;
a transmission line that connects the power conversion unit and the power transmission unit; and
a compensator that is disposed between the power conversion unit and the transmission line, wherein
the compensator includes
an inductive reactance element that has an inductive reactance that is greater than an inductive reactance of the transmission line, and
a capacitor that reduces an inductive reactance that is a sum of an inductive reactance of the transmission line and an inductive reactance of the inductive reactance element, wherein the inductive reactance element and the capacitor of the compensator are connected.
