An inspection data management method comprising: a step of inspecting products with an inspection apparatus (11a, 11b, 11c) for inspecting products in a production line to determine whether the products produced are defective; a step of storing inspection result data representing results of a plurality of product inspections with the inspection apparatus (11a, 11b, 11c) in an apparatus-side inspection result database (14a, 14b, 14c); a step of determining whether a sending condition for sending the inspection result data to a management server is satisfied; a step of extracting data that has not been sent to the management server from the inspection result data stored in the apparatus-side inspection result database (14a, 14b, 14c); and sending, if the sending condition is fulfilled, the data to the management server; a step of receiving, with the management server, the inspection result data sent by the inspection apparatus (11a, 11b, 11c); and a step of storing the received inspection result data in a server-side inspection result database of with the management server; a step of storing information relating to the inspection of the product by the inspection apparatus in a server-side inspection program database, wherein the information relating to the inspection of the product comprises inspection criteria for determining whether the product produced is defective; and a step of converting, at the management server, the received inspection result data that is stored in the server-side inspection result database into relational data, based on the information relating to the inspection of the product that is stored in the server-side inspection program database; a step of storing the converted relational data converted in a statistical analysis database, which is a relational database, in order to perform statistical analysis at the management server. a step of inspecting products with an inspection apparatus (11a, 11b, 11c) for inspecting products in a production line to determine whether the products produced are defective; a step of storing inspection result data representing results of a plurality of product inspections with the inspection apparatus (11a, 11b, 11c) in an apparatus-side inspection result database (14a, 14b, 14c); a step of determining whether a sending condition for sending the inspection result data to a management server is satisfied; a step of extracting data that has not been sent to the management server from the inspection result data stored in the apparatus-side inspection result database (14a, 14b, 14c); and sending, if the sending condition is fulfilled, the data to the management server; a step of receiving, with the management server, the inspection result data sent by the inspection apparatus (11a, 11b, 11c); and a step of storing the received inspection result data in a server-side inspection result database of with the management server; a step of storing information relating to the inspection of the product by the inspection apparatus in a server-side inspection program database, wherein the information relating to the inspection of the product comprises inspection criteria for determining whether the product produced is defective; and a step of converting, at the management server, the received inspection result data that is stored in the server-side inspection result database into relational data, based on the information relating to the inspection of the product that is stored in the server-side inspection program database; a step of storing the converted relational data converted in a statistical analysis database, which is a relational database, in order to perform statistical analysis at the management server.
