PROBLEM TO BE SOLVED: To obtain a wiring pattern preparation system capable of collectively performing similar modification even of a plurality of linear patterns with a simple operation at the time of preparing a wiring pattern based on component arrangement data. SOLUTION: When center lines, etc., have to be modified after the center lines and a wiring pattern which are in a form being before preparing a thick wiring pattern are prepared, an input device 30 first, collectively selects the plurality of center lines, etc., and also designates a point and a line to be reference to modification change. Then, an arithmetic processing unit 10 changes the arrangement and shapes of the plurality of center lines at a time while maintaining the constituting relations of components constituting the center lines, etc., according to this designation.
