CORD-LIKE HEATER AND PLANAR HEATER

摘要

Provided are a cord-like heater which can be used for applications requiring fire-resistant properties, and a planar heater using the cord-like heater. A cord-like heater comprises a heat generating wire and a thermally bonded section which is formed on the outer periphery of the heat generating wire. The heat generating wire is formed by winding electrically conductive element wires on a core wire and applying insulation coating on the outer periphery of the wound electrically conductive element wires, or is formed by aligning parallel to each other or twisting together electrically conductive element wires coated with insulation coating. The thermally bonded section consists of a flame-resistant polymer composition, and the cord-like heater is configured to have flame-resistant properties satisfying a horizontal burning test in accordance with UL1581.
