A safety evaluation method according to the present disclosure includes preparing a sample for secondary battery electrode evaluation in which a short circuit will occur by contact between components included in the sample, applying a predetermined pressure that will cause the contact between the components to an area of the sample set as a secondary battery internal short circuit simulation contact area, applying a current between I probes in contact with the sample, obtaining resistance by measuring a potential difference between V probes which are separate from the I probes, obtaining a graph of a change in resistance with a change in distance between the V probes, calculating a short circuit resistance of the area from y-intercept of the graph, and predicting a heat generation amount of the area from the short circuit resistance.
