A wire harness production supporting device, which is configured to produce a wire harness by in turn laying out a plurality of electric wires on a full scale wire laying out image on a display device of a work bench, comprising: a control device configured to include an administrating display device configured to display a progress status of operations; a time recording section configured to, each time one of the plurality of electric wires is laid out, store a time at which the one of the plurality of electric wires has been laid out, in a storing section; and a progress status administrating section configured to obtain a progress status of the production of the wire harness based on the time at which the one of the plurality of electric wires has been laid out having been stored in the storing section; an identification code presenting means configured to present, on the display device, an identification code of the one of the plurality of electric wires to be laid out; a reading in means configured to read in the identification code of the one of the plurality of electric wires to be laid out from the display device, each of the plurality of electric wires to be laid out being fitted with a respective identification mark thereon, said reading means also being configured to read the identification mark of said one of said electric wires; wherein the time recording section is configured to store, in the storing section, a time at which the identification code of the one of the plurality of electric wires to be laid out has been read in by the reading in means; a continuity checking section that is configured to perform a continuity checking processing on the one of the plurality of electric wires to be laid out, wherein the time recording section is configured to store, in the storing section, a time at which the continuity checking processing of the one of the plurality of electric wires to be laid out with the continuity checking section has been completed a correspondence decision section, that is configured to judge as to whether the respective identification mark and the respective identification code of each of the plurality of electric wires to be laid out having been read in by the reading in means are in correspondence with each other, wherein, when the correspondence decision control section judges the respective identification mark corresponds to the respective identification code, the time recording section stores, in the storing section, a time at which the identification code has been read or a time at which a judgement has been made that the respective identification mark corresponds to the respective identification code as the time at which the identification code has been read. a control device configured to include an administrating display device configured to display a progress status of operations;
