An electrical connection box for installation in a vehicle includes a bus bar to electrically and thermally interconnect a plurality of electrical components electrically connected to a power storage device or in-vehicle load installed in the vehicle, a casing to house the plurality of electrical components and the bus bar, and an insulating heat dissipation member thermally connected to the bus bar and the casing, with at least two of the plurality of electrical components being disposed adjacent to each other, and the bus bar dissipating heat from the two electrical components via the heat dissipation member.

Electrical connection box

Provided is an electrical junction box capable of housing an electric component while absorbing the tolerance of the electric component. The electrical junction box is an electrical junction box that is to be mounted in a vehicle, including: a casing that forms an outer shell; and a fixation member that fixes, to the casing, an electric component that is to be electrically connected to a vehicle-mounted load or an electricity storage device mounted in the vehicle, wherein a slit for absorbing a tolerance associated with external dimensions of the electric component is provided in the fixation member.
