PROBLEM TO BE SOLVED: To provide a tube for heating a fluid which heats the whole length thereof more uniformly than conventionally. SOLUTION: The tube to raise the temperature of a fluid has a conductive heat-generating layer 3 in the longitudinal direction thereof, and heats the fluid by making the conductive heat-generating layer 3 generate heat by applying a voltage. It heats a fluid more effectively than the case where heat is transferred to a fluid by an externally attached heater or by contacting a heat source with the tube. Especially in the case of heating an electrically insulative fluid as an object, the tube has an advantage of carrying out heating in the simple structure. COPYRIGHT: (C)2006,JPO&NCIPI
