<P>PROBLEM TO BE SOLVED: To provide a tube for fluid heating that easily maintains current-carrying performance. <P>SOLUTION: A tube 1 for fluid heating which has a flow passage 30 along a length direction includes a conductive heat generating layer 11 formed covering the flow passage 30 from outside in a section crossing the length direction, and a first electrode 12 and a second electrode 13 which are arranged apart from each other in the section while coming into contact with the conductive heat generating layer 11, and also arranged along the length direction respectively. The first electrode 12 and second electrode 13 which are both applied with a voltage from outside are formed to have smaller volume resistivity than that of the conductive heat generating layer 11 which generates heat with a current flowing between the first electrode 12 and second electrode 13. The conductive heat generating layer 11, first electrode 12, and second electrode 13 are all made of materials including resin. <P>COPYRIGHT: (C)2012,JPO&INPIT |
