PURPOSE: An electromagnetic induction vacuum heating apparatus is provided to maximize energy efficiency because an electromagnetic field generating in a coil is concentrated on a pipe. CONSTITUTION: An electromagnetic induction vacuum heating apparatus comprises a paramagnetic pipe(10), a cylindrical insulating unit(20), a coil(30), a magnet(50), a cover unit(60), and a bobbin unit(40). The paramagnetic pipe comprises a water channel and is spirally wound. The insulating unit encloses the pipe and blocks the outflow of the heat generating in the pipe. The coil is spirally wound to enclose the insulating unit. If alternating current flows, the coil generates electromagnetic fields. The magnet encloses the coil. The inner circumference of the magnet is n-pole and the outer circumference thereof is S-pole. The cover unit encloses the pipe, insulating unit, coil, and the magnet and the inside thereof is a vacuum state. The bobbin unit is wound on the coil and fixes the wound coil.
