Abstract: An electrical connection box includes an insulating plate made of resin that supports an input load applied on a connection terminal to be connected to an electrical part. The insulating plate is contained between upper and lower cases and provided with a honeycomb structure portion penetrating through the insulating plate in a plate thickness direction. It thus becomes possible to provide an electrical connection box of a novel structure provided with an insulating plate not only ensuring strength with a smaller amount of resin but also capable of enhancing heat dissipation.

Abstract: An internal circuit structural element including a bus bar circuit structural element formed by a bus bar having a selectively cuttable portion that is formed into different types of routing configurations as a bus bar circuit by selectively cutting the portion, and a printed wire circuit structural element formed by a printed-circuit board having a selective energization portion obtained by dividing a printed wire that is formed into different types of routing configurations as a printed wire circuit by selectively attaching a jumper member that bridges across a divided portion of the printed wire to the selective energization portion.

Abstract: A permanent part attachment portion and an additional part attachment portion are provided to a case. A terminal portion of a permanent bus bar is disposed in the permanent part attachment portion, and a terminal portion of an additional bus bar is disposed in the additional part attachment portion by allowing the additional bus bar to be contained in the case in a removable manner. It thus becomes possible to provide an electrical connection box that is adaptable to an addition of an electrical part without changing a die used to mold the case and/or a die used to form the bus bars.
