<p>PROBLEM TO BE SOLVED: To provide a radiation structure of an electric junction box which is excellent in its radiation effect and capable of attaining size reduction without causing a cost increase. SOLUTION: In an electric junction box 20, insulating substrates 26 wired with bus bars 28 are provided inside an upper case 22 having component mounting parts 4 to which electronic and electric function components are attached, and male tab terminals 28a hung from the bus bar 28 on the insulating substrates 26 are electrically connected to the connecting terminals 2a of the electronic and electric function components 2 which faces inside the case through the component mounting parts 4. Inside the electric junction box 20, an insulating sheet 30 which covers the bus bars 28 exposed on the surface of the insulating substrate 26 and is passed through by the male tab terminals 28a of the bus bars 28, and a metallic plate 34 in which only the peripheral parts 36 of insertion holes 32 inserted by the male tab terminals 28a passing through the insulating sheet 30 is outsert-formed out of insulating resin, are disposed in a layered manner.</p> |
