SHEET HEATER AND MANUFACTURING METHOD OF HEATING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a sheet heater without increasing manufacturing cost; and to provide a manufacturing method of a heating element used for the sheet heater. SOLUTION: A strip-like thin plate formed of a resistive member is so formed that linear parts 22 are positioned between meandering parts 21 by appropriately partially cutting it from both right and left sides. The positions of the meandering parts 21 are allowed to be changed by folding back the linear parts 22 when it is arranged in an insulation sheet 11. COPYRIGHT: (C)2007,JPO&INPIT
