    • The invention provides a method of calculating an equivalent circuit, which reduces the number of elements constituting a network to a large extent with a target accuracy secured. The method of the invention calculates an equivalent circuit by a computer, with regard to an object that has a conductor, a dielectric to support the conductor, and plural input/output terminals to the outside. Step 1 in the method receives inputs of geometry information to specify a shape of a conductor in a circuit board being the object of determining the equivalent circuit, and material information to specify a material of the circuit board; Step 2 partitions the shape of the objective conductor into meshes on the basis of the geometry information received, and creates mesh data to be expressed; Step 3 calculates a nodal admittance matrix from the mesh data, and stores the result; step 4 calculates the number of nodes and the number of independent networks on the basis of the mesh data, determines an incidence matrix, and determines the structure of an equivalent network by means of the calculated nodal admittance matrix and incidence matrix; and Step 5 determines the values of elements of the equivalent network.
