Abstract: There is disclosed an electric box which can facilitate a connecting operation of electric-box-side coupler and lead-wire-side coupler while suppressing attachment of dust or the like to connecting portions between the couplers. In the electric box, electric components are stored in an outer case, the electric box is connected to external lead wires, the electric box includes the electric-box-side coupler detachably connected to the lead-wire-side coupler attached to distal end of the lead wire, and a coupler receiving portion constituted in the outer case, the electric-box-side coupler selectively has a received state in which the coupler is positioned in the coupler receiving portion and an exposed state in which the couplers are exposed from the coupler receiving portion, and the electric-box-side coupler and the lead-wire-side coupler connected to the electric-box-side coupler are detachably received in the coupler receiving portion in the received state.
