FAR INFRARED RADIATION HEATER SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a far infrared radiation heater substrate that is superior in thermal shock resistance, and in far infrared radiation performance. SOLUTION: This is the far infrared radiation heater substrate 4 comprised that a pattern layer 2 composed of a metal heating resistor is baked on a crystallized glass 1. It is preferable that the pattern layer 2 is coated by an over coat glass 3.
