An electrical connection box includes a box main body having an opening portion in an upper end portion at a time of installation, and an upper cover that blocks the opening portion at the time of installation. The box main body has an insertion wall portion continuously formed along an outer circumference of the box main body in the upper end portion at the outer circumference of the box main body. The upper cover has a groove portion continuously formed along an outer circumference of the upper cover in a lower end portion at the outer circumference of the upper cover. Here, the insertion wall portion is inserted into the groove portion from lower side when the opening portion of the box main body is blocked. At least one rib protruding downward from a bottom portion of the groove portion is formed in the groove portion.

An electrical connection box includes a housing, a tool and a tool holding portion. The tool includes a main body in which a holding hole is formed, and a pinching portion. The tool holding portion includes a holding main body, a rotation regulating portion and a protrusion protruding on an opposite side from a side of the rotation regulating portion with the holding main body interposed therebetween. The protrusion is formed to face an opposite side from a side of the pinching portion with the holding hole interposed therebetween in the main body in an insertion direction in the holding state, and comes into contact with the main body in a state in which the pinching portion is positioned in a pulling direction compared to a position of the main body from the holding state.
