PROBLEM TO BE SOLVED: To provide an interruption controller etc. for preventing the generation of the overhead of hardware setting change processing necessary for the change of an interruption order. SOLUTION: The interruption controller 10 generates an interrupting signal and an interrupting vector corresponding to a plurality of interruption factors ranging from the first interruption factor to the n-th interruption factor, and the interruption controller 10 is provided with: an interruption factor storing part 40 which receives a plurality of interruption factor signals ranging from the first interruption factor to the n-th interruption factor, and stores an interruption factor value corresponding to the interruption factor; an interrupting vector generating circuit 60 which generates an interrupting vector based on a priority order made to correspond to each interrupting factor; and a priority order cyclic movement (rotation) circuit 80 which executes the cyclic movement of the priority order of the interruption factors ranging from the first interruption factor to the n-th interruption factor when receiving the reset signal of the interrupting factor whose priority order is the highest among the interrupting factor signals ranging from the first interrupting factor to the n-th interrupting factor.
