NOVELTY - The box has an electric wire terminal (48) attached to an aluminum electric wire (44) penetrated through an electric wire terminal penetration hole (30) opened to a side i.e. lower surface (24), of a box main body (12) succeeding a component terminal penetration hole (28a, 28b). An upper opening part (60) of an electrical component mounting part i.e. fuse mounting part (26), mounted with an electrical component is covered with a coating layer (58) by photoresist. An opening formed along upper direction of the component terminal penetration hole is covered by the coating layer.    USE - Electrical-connection box e.g. relay box and junction box, for connecting an electrical component i.e. fuse, and an electric wire mutually in an engine compartment of a motor vehicle. Can also be used for a relay and a battery.    ADVANTAGE - The upper opening part of the electrical component mounting part mounted with the electrical component is covered with the coating layer by the photoresist such that water entraps into the component terminal penetration hole via a clearance gap between the electrical component mounting part and the electrical component even if the box pours the water and the water exerts from the upper direction of the electrical component mounting part, so that pouring of the water on a connection part of the electric wire terminal and the electric wire with which the component terminal is mounted can be prevented and fear of corrosion of the electric wire by pouring the water can be reduced. The box avoids a need to provide special mold process to the connection part with the electric wire terminal of the aluminum electric wire even if the aluminum electric wire is provided with high possibility of electric wire corrosion, so that cost of the box can be reduced.    DETAILED DESCRIPTION - The box main body is a synthetic resin made box main body. The electrical component is a fuse (42). An INDEPENDENT CLAIM is also included for a method for manufacturing an electrical-connection box.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a box main body.
