SHEET HEATER

摘要

PROBLEM TO BE SOLVED: To provide a sheet heater used in cooking having a structure in which heat from a heating element is hard to be transferred to a heat insulator and which can obtain high radiating amount and prevents the heating element from being corroded by salt. SOLUTION: Ribbon shape heating element 7 having gathers is inserted into a groove 9 formed on the upper surface of a heat insulator 8 in such a form that the tip of the heating element thereof does not protrude from the top surface of the insulator and side thereof is opposed to a heated object. Therefore, radiating area can be remarkably improved and prevents drooping of the heating element during heating.
