ELECTRICAL CONNECTION BOX

摘要

PROBLEM TO BE SOLVED: To provide an electrical connection box which suppresses that a temperature becomes locally high.

SOLUTION: The electrical connection box 10 includes: a casing 11; and a circuit structure 12 stored in the casing 11. The circuit structure 12 includes a plurality of first bus bars 21 arranged by leaving intervals; and a synthetic resin material 22 which is arranged between the plurality of adjacent first bus bars 21 and is brought into close contact with the first bus bars 21. A heat transfer coefficient of the synthetic resin material 22 is larger than that of air. Since heat generated from the first bus bar 21 can be transmitted to the synthetic resin material 22 upon electrification, the temperature of the electrical connection box 10 is suppressed from becoming locally high.
