<p>PROBLEM TO BE SOLVED: To discharge heat being generated inside an electrical connection box to the outside without increasing the size of the electrical connection box, changing the area of an electronic substrate part, or the like, by connecting a terminal being provided at a wiring board in a case and a heat sink outside the case to a connection terminal that is sealed to the case of the electrical connection box. SOLUTION: A fuse that mounted to a case 25 of an electrical connection box A1, a relay 27 and a coil provided at an electronic substrate part 26 are connected to a heat sink 33 via each tab terminal 30 and a connection terminal 32, and generated heat is discharged to the outside of the electrical connection box A1 via the heat sink 33. Also, a cover wall 34 for covering the heat sink 33 is provided outside a wall 25a, an air supply port 35 and an outlet 36 are provided at the cover wall 34, the heat sink 33 is cooled by air being taken in from the outlet 36, and the air exhausted from the outlet 36, thus discharging heat being generated in the electrical box to the outside without, increasing the size of the electrical connection box or changing the area the electrical substrate part 26.</p> |
