Abstract: A laundry apparatus is provided. The laundry apparatus may include a cabinet, a tub provided in the cabinet and defining an internal space, the tub having an opening formed in a front of the tub, a drum rotatably provided in the internal space of the tub and being made of a conductor, and an induction heater provided at an outer circumferential surface of the tub. The induction heater may heat the drum by generating an electromagnetic field and may include a coil that uses a supplied electric current to generate an eddy current in the drum by generating a magnetic field, and a coil arranging portion provided at the outer circumferential surface of the tub. The coil may be arranged on the coil arranging portion such that coils of the coil are spaced a predetermined distance apart from each other while being wound from a front direction to a rear direction of the tub.
