Abstract

The present invention relates to a contactlessly chargeable heater. In one example, the contactlessly chargeable heater includes: an induction patch emitting magnetic field by means of current applied to an inner coil; and a heating body, receiving the magnetic field from the charging patch to perform a contactless charging operation, and including a conductive metal yarn for emitting heat via the power generated through the contactless charging operation. The conductive metal yarn is woven together using threads within the heating body.
