PROBLEM TO BE SOLVED: To provide a method for evaluating a deviated distribution of a resin without requiring much time for determination while suppressing the scattering of the evaluation results by the observer. SOLUTION: On the occasion of measurement of the warpage of the composite material, after keeping a composite material at a sate of B stage obtained by impregnating a base material being a textile or non-woven textile with a resin varnish, then drying it, after giving energy to it by heating so as for the material to have a temperature higher than 100°C and not higher than 300°C, a screening plate with mesh structure with at least 330 mesh is arranged between a blow out hole heated for hot air and the composite material described above. On occasion of the evaluation of the warpage of the composite material A, it can be not necessary to make the extremely small cross-section expanded nor to make measure the amount of the resin in the extremely small cross-section.
