Platinum temperature sensor
 A platinum temperature sensor includes a sensor body formed of a cylindrically rolled plate-type ceramic sheet and a platinum resistance pattern provided on the surface of the ceramic sheet. The platinum resistance pattern is provided on the inner or outer surface of the ceramic sheet. The sensor may further include lead wires, and the ceramic sheet may have through holes for lead wires, which are conductively connected to both ends of the platinum resistance pattern. The lead wires are connected to the platinum resistance pattern. The sensor may further include resistance regulating lines provided on the outer surface of the ceramic sheet, and the ceramic sheet may have through holes reaching the intermediate portion of the platinum resistance pattern. The resistance regulating lines are connected to the platinum resistance pattern through a plurality of said through holes, and may be selectively cut to adjust the resistance of the platinum resistance pattern.
