Disclosed is the provision of a method for assisting the detection of pancreatic cancer, the method assisting the detection of pancreatic cancer with high accuracy. In the method for assisting the detection of pancreatic cancer, the amounts of (1) miR-122-5p and (2) at least one miRNA selected from the group consisting of miR-16-5p, miR-19b-3p and miR-25-3p, all of which are contained in a test sample separated from a living body, are used as indicators. A larger amount of miR-122-5p and a smaller amount of at least one miRNA selected from the group consisting of miR-16-5p, miR-19b-3p and miR-25-3p than those in a healthy individual indicates that the living body is more likely to have developed pancreatic cancer.
