An electrical connection box includes a circuit casing comprising a casing for accommodating a circuit structure therein and a cover, a lower connector housing disposed on the lower surface side of the circuit casing and connectable to an external connector, and a plurality of lower on-bus-bar terminals for electrically connecting between the circuit structure and the lower connector housing. Each lower on-bus-bar terminal is disposed along a cabling path horizontally traversing the inside of the circuit casing and leads into the lower connector housing through the ceiling portion of the housing. In the circuit casing, a waterproof wall is provided for covering the ceiling portion from above. Water having intruded into the circuit casing drops onto the waterproof wall, and thereby is prevented from reaching the ceiling portion of the lower connector housing disposed below. Thus the water is prevented from accumulating on the ceiling portion, and consequently short-circuiting among the lower on-bus-bar terminals disposed on the ceiling portion is prevented.
