PURPOSE:To provide the packing structure of an electric connection box whose manufacturing cost is low, which can reduce the number of working persons and whose sealing performance is stable. CONSTITUTION:By using an injection nozzle 10 which is controlled automatically by a robot or the like, a liquid packing material 11a is injected directly into a groove in a waterproof cover 4 with which an electric-connection-box body is covered, and the packing material is hardened inside the groove 4a after it's injection. The groove width of every corner part 4c in the packing groove 4a is made wider than that in every straight-line party 4b so as to increase a volume. |
