PURPOSE: A wireless power transmission circuit and a wireless power transmitter and receiver are provided to omit a coating removal process of a litz wire by forming a coil in which a litz wire with a general single wire are combined. CONSTITUTION: A wireless power transmission circuit comprises a litz coil part, a single wire coil part, and a capacitor. The litz coil part is formed by winding a litz wire. The single wire part is formed by winding the single wire while being closer to the litz coil part. A capacitor is connected to the single wire coil part. Either the litz coil part or the single wire coil part is wound in a solenoid-type. Either the litz coil part or the single wire coil part is wound in a spiral type.
