<P>PROBLEM TO BE SOLVED: To provide a heater that can quickly increase the temperature of a lubrication-based fluid without excessively heating the lubrication-based fluid even when the heater has a small size. <P>SOLUTION: A heater includes: a cylindrical honeycomb structure 4 having a partition wall 1 that dividingly forms a plurality of cells 2 extending from one end surface to the other end surface which serve as a passage of a lubrication-based fluid, and having an outer peripheral wall 3 located on the outermost periphery; and a pair of electrode parts 21 connected to a side surface of the honeycomb structure 4 via a conductive connection part 23. The partition wall 1 is made of a material composed mainly of ceramics, and generates heat by the passage of electric current. The electrode parts 21 have such a shape that the area of a connection part of the electrode parts 21 is smaller than the area of a shape surrounding the outer periphery of the electrode parts 21. Alternatively, the shape of the electrode parts 21 is a rectangle whose corners are curvedly formed. The conductive connection part 23 is formed by firing a conductive connection material at 60-200°C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
