PROBLEM TO BE SOLVED: To evaluate a flange shape as to gap corrosion by quantifying a corrosion phenomenon arising within a gap in a flange of a product by a finite element method. SOLUTION: In this analyzer 100, first, a model of a gap shape of a flange is generated by a model generator 111. Nextly, when initial conditions and an equation necessary for analysis are thereinto input, the equation is solved by an analysis processor 112 to find electric potential distribution on the gap shape and concentration distribution of ferric ions with iron that forms the flange liquated thereinto. Thereafter, an optimum flange shape reducing the quantity of corrosion is determined by a shape evaluator 113 while referring to the found potential distribution and concentration distribution.
