PROBLEM TO BE SOLVED: To provide a structure and a method capable of more easily measuring a stress caused by volume shrinkage due to a chemical reaction of a target resin.SOLUTION: A stress measurement method includes a step of injecting a sample into the inside of a sample ring arranged on a sample table. At least an inner surface of the sample ring is structured of a material having small affinity relative to the sample. The stress measurement method includes: a step of arranging a link member while being brought into contact with the sample injected into the sample ring in an opposite side to the sample table; a step of adding a factor for causing a curing reaction or a shrinkage reaction in the sample; and a step of measuring a magnitude of a stress received by the link member over a predetermined time.SELECTED DRAWING: Figure 4 |
