An electronic apparatus capable of performing efficient dissipation of heat generated within the apparatus, thereby making uniform the exterior temperature of the apparatus, without increasing the manufacturing costs and size of the apparatus. The electronic apparatus includes a circuit board having an electric component as a heat source mounted thereon, a thermal connection member forming part of a battery chamber, a heat pipe having one end connected to the electric component and the other end thermally connected to the thermal connection member, and a battery insertion part forming part of the battery chamber. The battery insertion part is disposed closer to a battery insertion port than the thermal connection member is. The battery insertion part is formed of a material lower in thermal conductivity than the thermal connection member.
