PROBLEM TO BE SOLVED: To provide a material direction analysis method capable of easily setting a material direction of a reinforcing fiber. In this material direction analysis method, a step of dividing a region along the surface shape of a portion where a reinforcing fiber portion 3 is arranged into minute elements E1 to generate a numerical analysis model M1 and a generated numerical analysis model By solving the Laplace equation for a predetermined physical quantity under the step of setting the boundary condition for M1 and the set boundary condition, the physical quantity in the numerical analysis model M1 and the direction are regarded as the material direction of the reinforcing fiber 3. It includes a step of calculating the gradient of the physical quantity. [Selection diagram] Fig. 1
