To provide a structure for a fuse resistor which minimizes variations in circuit interruption characteristics by each fuse resistor.

The fuse resistor includes a hollow rectangular parallelepiped shape box; a resistance element arranged inside the box; and a cement layer surrounding the periphery of the box, and the box includes a storage space for storing an element body; and a partitioning wall arranged adjacent to the storage space and separating an operation space which has the operation part of a fuse mechanism arranged.
