Claim Text:
1. An electrical junction box comprising: a casing; and an electrical component that is accommodated in the casing and has an electrical component case and a terminal portion, the terminal portion being accommodated in the electrical component case and having a contact, wherein a small heat amount-generating region, that generates a smaller amount of heat than the electrical component generates when current flows through the electrical component, is formed in the casing, the electrical component is disposed such that the contact is located on the small heat amount-generating region side, the casing accommodates an electrical component-mounting board on which the electrical component is mounted, and a small heat amount-generating board that is disposed in the small heat amount-generating region and generates a smaller amount of heat than the electrical component-mounting board generates when current flows through the electrical component, and the electrical component is disposed such that the contact is located on the small heat amount-generating board side.
