PROBLEM TO BE SOLVED: To provide an electronic apparatus in which, when water splashes on a part, etc. of an automobile or a motorcycle, the water does not permeate into a part in which heat is required to be dissipated particularly, thereby raising reliability in the part. SOLUTION: In the electronic apparatus, electronic parts which generate heat are adhered and mounted to a base of a metal casing, and a heat sink is attached to the metal case to dissipate the generated heat outward. A part around a contact plane which attaches the heat sink in the metal case and below the electronic parts which generate heat is enclosed with a groove. Specifically, the groove is formed to have a depth of 0.8 mm or more and a width of 1 mm or more. COPYRIGHT: (C)2004,JPO
