A wireless power transmitting device includes: a transistor configured to output a signal corresponding to a set operating frequency, based on an input signal and a driving voltage; a matching circuit connected with the transistor; a transmission coil connected with the matching circuit; an LC resonance circuit connected in parallel between the transistor and the matching circuit and configured to transfer a signal corresponding to at least one harmonic frequency of the operating frequency; and an impedance sensing circuit connected with the LC resonance circuit and configured to sense a load impedance of the wireless power transmitting device based on the signal corresponding to the at least one harmonic frequency transferred through the LC resonance circuit. The matching circuit is configured to provide impedance matching with the sensed load impedance by adjusting an impedance of the matching circuit or an impedance of the transmission coil.
