A wire harness continuity inspection method comprising: a reference step of referencing specification codes allocated to each partitioned area for every partitioned area dividing a vehicle space; a first specification step of specifying a first partitioned area to which the most specification codes are allocated from among the partitioned areas; a second specification step of specifying a second partitioned area to which the most specification codes are allocated from among the partitioned areas except the first partitioned area, and to which at least one of the specification codes in common with the specification codes allocated to the first partitioned area is allocated; a third specification step of specifying a third partitioned area to which the most specification codes are allocated from among the partitioned areas except the first partitioned area and the second partitioned area, and to which at least one of the specification codes in common with the specification codes allocated to the first partitioned area and the second partitioned area is allocated; a creation step of creating, region-based connector or wiring information in numbers equal to the number of combinations of a first wire harness, a second wire harness, and a third wire harness, wherein the region-based connector or wiring information describes at least the first wire harness being one of the first wire harnesses arrangeable in the first partitioned area, the second wire harness being one of the second wire harnesses arrangeable in the second partitioned area, and the third wire harness being one of the third wire harnesses arrangeable in the third partitioned area; and an inspection step of inspecting presence or absence of an error in a connection of electric wires in the created region-based connector or wiring information. a reference step of referencing specification codes allocated to each partitioned area for every partitioned area dividing a vehicle space; a first specification step of specifying a first partitioned area to which the most specification codes are allocated from among the partitioned areas; a second specification step of specifying a second partitioned area to which the most specification codes are allocated from among the partitioned areas except the first partitioned area, and to which at least one of the specification codes in common with the specification codes allocated to the first partitioned area is allocated; a third specification step of specifying a third partitioned area to which the most specification codes are allocated from among the partitioned areas except the first partitioned area and the second partitioned area, and to which at least one of the specification codes in common with the specification codes allocated to the first partitioned area and the second partitioned area is allocated; a creation step of creating, region-based connector or wiring information in numbers equal to the number of combinations of a first wire harness, a second wire harness, and a third wire harness, wherein the region-based connector or wiring information describes at least the first wire harness being one of the first wire harnesses arrangeable in the first partitioned area, the second wire harness being one of the second wire harnesses arrangeable in the second partitioned area, and the third wire harness being one of the third wire harnesses arrangeable in the third partitioned area; and an inspection step of inspecting presence or absence of an error in a connection of electric wires in the created region-based connector or wiring information.
