Beschreibung
Zusammenfassung:	The invention provides an in-vehicle controller equipped with a heat radiation coating film which can efficiently radiate heat from a high temperature portion such as a heat generating body to a casing. An in-vehicle controller includes a heat radiation coating film, wherein the heat radiation coating film includes a first region 302a that has a first boundary surface 305 abutting on a base material 301, and a second region 302b that has a second boundary surface 306 where the heat radiation coating film abuts on air, wherein a thermal conductivity of the first region is higher than that of the second region, and wherein a thermal emissivity of the second region is higher than that of the first region.
