Relationship between measured values of characteristic parameters of disposable diapers and subjective evaluation data was investigated precisely. As subjective evaluation of water diffusion in disposable diapers is dynamic process related to the diffusion of water, evaluation conditions and the time are very important. Amount of pouring water should be less than the critical saturated region of diapers to obtain reliable subjective results. The sense of "sarasara(dry)" and "touch" agreed well in the case of wet diapers, and it might be very important to keep the surface to be dried to get comfortable disposable diapers. Correlation coefficients between each objective value and subjective data were calculated and it was shown that the sense of "sarasara" was evaluated by a new parameter of V<SUB>h</SUB>, that is, the peak value of remained water curve divided by the convergence time of the water. Further, "sarasara" was regressed with F<SUB>w</SUB>, that is, the diffusion rate in horizontal direction and F<SUB>h</SUB>, that is, the diffusion rate in vertical direction.
