PROBLEM TO BE SOLVED: To provide a deformation behavior predicting device of rubber material and a deformation behavior predicting method of rubber material capable of precisely analyzing at micro level a deformation behavior of rubber material having a complex network structure in which filler with a primary particle diameter of several dozen nm existing in the rubber material are connected in a number of several tens or more. SOLUTION: The method comprises taking two or more slice images by observing the surface of the rubber material with a predetermined shape compounded with rubber and filler using a FIB-SEM apparatus 11; converting to binarized images for distinguishing between rubber part and filler part contained in the taken respective slice images; laminating the binarized images in a predetermined distance to form a three-dimensional model; applying a constructive condition defining a relation between a strain and a stress of the rubber and filler based on the binarized values to the respective grate regions of the formed three-dimensional model; analyzing the deformation behavior using the three-dimensional model applied with the constructive condition; and predicting the deformation behavior of the rubber material from the analysis result by calculating a strain or stress distribution, distinguishing the distribution regions of strain or stress, and defining the positions of respective regions.
