PURPOSE: To increase heat efficiency by diffusing heat through a process for the transfer thereof from the external side of the bottom of a pot body to the internal side, and keeping the heat in contact with a heated object such as water over a wide area. CONSTITUTION: A plurality of irregular sections 4 is formed all around a bottom inside the non-magnetic material 1a of a pot body 1, including corner sections. As a result, heat applied to the external surface of the body 1 is diffused at a process for the transfer thereof to the internal side of the body 1, thereby expanding a contact area with a heated object such as water. |
