。[Claims for Utility Model Registration] (1) An oil heater installed in an oil passage, in which a heating element is printed, thermally sprayed, or plated on the outer circumferential side of a ceramic cylindrical body whose inner circumferential side becomes the oil passage. 1. An oil heater characterized in that the heating element is directly fixed with a heating element, and the heating element is covered with a protective layer made of an insulating material. (2) The oil heater is supported by two rings interposed between the oil passage and the inner peripheral surface of the oil passage, and one ring is electrically connected to one end of the heating element. The other ring is electrically connected to the other end of the heating element and conducts between the heating element and the inner peripheral surface of the oil passage. 2. The oil heater according to claim 1, wherein a heat insulating space is formed between the protective layer and the inner circumferential surface of the oil passage between both rings.
