PROBLEM TO BE SOLVED: To provide a system for calculating a wiring length of a wiring path passing an electronic component mounted on a printed wiring board and present in different networks. SOLUTION: This wiring length calculation system has: a wiring search means searching for the wiring path composed by continuation of graphics mutually in a connection state from a calculation start point; a distinction means distinguishing whether it is regarded that the wiring path is allowed to pass from one terminal of the prescribed electronic component to the other terminal or not based on a passage parameter recorded in a recording means when the searched wiring path is connected with the one prescribed terminal of the prescribed electronic component; a search continuance processing means performing processing such that the search for the wiring path is continued from the other terminal by a wiring path search means when it is regarded that it is allowed to pass as a result of distinction; and a calculation means adding wiring lengths of each wiring present on the wiring path from the calculation start point to a calculation end point when the calculation end point is present on the wiring path searched by the wiring path search means, and calculating the wiring length between the calculation points.
