Official abstract text for this publication.
A heater includes a heat generating member being conductive and configured to radiate heat rays by being fed with electric power, and a tubular member constituting of a metal and accommodating the heat generating member, wherein the heat generating member is composed of a material containing carbon at 80% or more by mass, the tubular member is composed of a material including one or more selected from platinum, rhodium, tungsten, iridium, and molybdenum, and an insulating material is not provided between the heat generating member and the tubular member.
Opening claim text (preview).
What is claimed is: 1 . A heater comprising: a heat generating member being conductive and configured to radiate heat rays by being fed with electric power; and a tubular member composed of a metal and accommodating the heat generating member, wherein the heat generating member is composed of a material containing carbon at 80% or more by mass, the tubular member is composed of a material including one or more selected from platinum, rhodium, tungsten, iridium, and molybdenum, an insulating material is not provided between the heat generating member and the tubular member, and the heat generating member is not in contact with the tubular member. 2 . The heater according to claim 1 , further comprising: a lead wire extending from an inside of the tubular member and electrically connected to the heat generating member, wherein a conductive heat-resistant material is provided between the heat generating member and the lead wire. 3 . The heater according to claim 2 , wherein an insulating member is provided around the conductive heat-resistant material.
