Abstract
A wireless power transmission apparatus is provided. The wireless power transmission apparatus includes an upper housing, a lower housing coupled to the upper housing, a substrate disposed between the upper housing and the lower housing, a transmit coil disposed between the upper housing and the substrate and formed by being wound in the form of rotating on the substrate, at least one temperature sensor including a pattern resistor, a resistance numerical value which varies with temperature, and a flexible printed circuit board (FPCB) on which the at least one temperature sensor is disposed. The pattern resistor is disposed on the FPCB in a pattern of being wound in a first direction from any first point on the FPCB to any second point different from the any first point on the FPCB around a central portion of the FPCB and being rewound in a second direction opposite to the first direction.
