The present invention enables structural optimization having a high degree of freedom, such as the allowance of a change in topology in a material domain &#x3a9;, and provides clear expression of the shape of optimum structures. The present invention defines a level set function &#x3c6;; updates the level set function &#x3c6;, under a predetermined constraint condition, so as to bring a performance of a structure, such as a rigidity, close to a target value; moves the boundary &#x2202;&#x3a9; between the material domain &#x3a9; and a void domain; allows a change in topology in the material domain &#x3a9;, which is associated with the update of the level set function &#x3c6;, to form a new void domain in the material domain &#x3a9;; and moves the boundary &#x2202;&#x3a9; between the new void domain and the material domain &#x3a9;.
