To provide an electrical junction box of novel structure capable of bringing a heat dissipating member into contact with a surface of an electric component stably, while reducing contact pressure of the heat dissipating member on the electric component.SOLUTION: The electrical junction box includes: a box body 12 provided on a surface 14 with a component mounting unit 22 on which an electrical component 30 is mounted; and a cover member 16 for covering the surface 14 of the box body 12. While, on an inner surface 48 of a top wall unit 42 of the cover member 16, a heat dissipating member holding unit 52 protruding toward the electric component 30 is provided, a plastic heat dissipating member 64 held by the heat dissipating member holding unit 52 is brought into contact with a surface 66 of the electric component 30.SELECTED DRAWING: Figure 2
