A strength evaluation method is a strength evaluation method for a composite material in which a plurality of fiber layers are laminated and includes a meandering state measuring process of measuring a meandering state of fibers of the plurality of fiber layers in a direction along the fiber layers, a meandering thickness measuring process of measuring a meandering thickness that is a thickness in a lamination direction of a part in which meanderings of fibers of the plurality of fiber layers occur, and a strength evaluation process of evaluating a strength of the composite material based on the meandering state and the meandering thickness.
