PURPOSE: A mold for making a gravity casting type cooker and a cooker manufacturing method using the same are provided to prevent the degradation and dissipation of a magnetic force in case of long time use by attaching a magnetic heating plate to an upper mold via an electromagnet module and a magnetic medium. CONSTITUTION: A cooker manufacturing method using a mold for making a gravity casting type cooker is as follows. A magnetic heating plate is set in a lower mold(3). An upper mold comprising a plurality of magnetic media(24) connected to an electromagnet module(25) and a control box(26) for supplying power to the electromagnet module is meshed with the lower mold and power is supplied to the electromagnet module through the control box so that the magnetic heating plate is attached to the magnetic media. Molten non-ferrous metal is injected into the meshed upper and lower molds and voltage is alternately applied to the electromagnet module for a set time, thereby casting a cooker with the magnetic heating plate exposed on the bottom. The cooker is separated from the upper and lower molds.
