To provide an analyzer for accurately analyzing the result of an impact test.SOLUTION: An impact test analysis apparatus acquires a load displacement curve which shows the relation between the load acquired by an impact test and displacement, acquires a fracture surface picture which photographed the fracture surface of the test piece of the impact test, and analyzes a fracture surface picture. Two or more imaging ranges which have the mutually different characteristic are detected. A first presumption model defines the relation of an area of the load displacement characteristic domain corresponding to each imaging range formed when two or more imaging ranges of each divides the domain surrounded by a rate, load displacement curve, and axis of coordinates of area which account for a fracture surface based on a predetermined turning point in the load displacement curve, A load displacement characteristic domain is computed and a turning point is computed based on the computed load displacement characteristic domain based on the load displacement curve for analysis, and the imaging range for analysis, and from the domain surrounded by the load displacement curve and axis of coordinates for analysis.SELECTED DRAWING: Figure 1
