The present invention provideS a connecting rod fracture splitting apparatus and a fracture splitting method which achieve high circularity of a crank pin hole and ensure smooth operation of an engine, and the like. A fracture splitting jig is fitted into a crank pin hole of a connecting rod, and a fracture load is applied in a longitudinal direction of the connecting rod via the fracture splitting jig to thereby fracture a big end of the connecting rod. A mandrel as the fracture splitting jig is divided into four parts to be separable from each other in a longitudinal direction of the connecting rod and in a direction orthogonal to the longitudinal direction. When the big end is fractured, a fractured portion thereof is allowed to come in contact with a predetermined portion of the fracture splitting jig.
