The utility model provides a core holder for breakthrough pressure. In the rock core holder, a rock core sample is arranged in a test assembly, two ends of the test assembly are respectively connected with a loading assembly and a detection assembly, and the loading assembly and the detection assembly are respectively used for applying an axial load to the rock core sample and detecting the breakthrough pressure of the rock core sample; an upper pressing cap of the detection assembly is mounted at the outlet end of the test assembly, and the lower end of an upper core plug abuts against the upper end face of the core sample; the upper pressure-bearing pressing cap is hermetically connected to the upper end of the upper pressing cap, and the lower end face abuts against the stepped end face of the upper core plug; the window cylinder is inserted into the upper core plug from the lower end of the upper core plug; the sealing pressure head is hermetically connected to the upper end of the upper core plug; a firs
