Abstract

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