Heater

摘要

There is disclosed a heater which does not excessively heat a lubricating fluid but can rapidly raise a temperature of the lubricating fluid, even when a size thereof is small. A heater 1 includes a honeycomb structure section 6 including partition walls 7 which contain a ceramic as a main component and generate heat by electrical conduction, and a plurality of cells 5 which are partitioned and formed by the partition walls 7 and extend through the honeycomb structure section from one end 9a to another end 9b to become through channels of a lubricating fluid; and a pair of electrodes 4 which become an anode 4a and a cathode 4b to come in contact with the honeycomb structure section 6, thereby conducting the electricity through the partition walls 7 of the honeycomb structure section 6.
