The invention provides an electronic apparatus having a metal core substrate including a metal plate, an insulating layer formed on the metal plate and a conductive layer formed on the insulating layer, and an electronic part, and to which the conductive layer and a terminal of the electronic part are connected. In the electronic apparatus, a member having a high thermal conductivity is arranged so as to be in contact with both of the metal plate and the electronic part. Accordingly, a heat radiating property of the electronic apparatus is increased.
