The wireless power transmission device includes a transmission coil including a first member, which has one end and the other end forming a first angle with a plane, and a second member, which is arranged on the plane and is connected to each of the one end and the other end of the first member, an impedance sensor for outputting a voltage value corresponding to an impedance change amount of a resonance circuit, which includes the transmission coil, a magnetic body having a side surface that is dented, the dented side surface facing a portion of the transmission coil, a motor for moving the magnetic body, memory storing one or more computer programs, and one or more processors communicatively coupled to the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the wireless power transmission device to receive the output voltage value from the impedance sensor, calculate the difference value between a reference voltage value and the received voltage value, determine control information about the motor on the basis of the calculated difference value, and drive the motor through the determined control information so as to control the distance between the magnetic body and the portion of the transmission coil.",
