Abstract
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 includes a honeycomb structure section including partition walls which contain a ceramic as a main component and generate heat by electrical conduction, and a plurality of cells which are partitioned and formed by the partition walls and extend through the honeycomb structure section from one end to another end to become through channels of a lubricating fluid; and a pair of electrodes which become an anode and a cathode to come in contact with the honeycomb structure section, thereby conducting the electricity through the partition walls of the honeycomb structure section.
