To provide a connecting rod whose flexural rigidity of a broken portion and separating load can be enhanced, and a method for manufacturing the same.

A connecting rod member is cut and divided at both side portions of a through-hole into a rod section and a cap section, and then both the sections are fastened by a fastening member after division to form the connecting rod. In the connecting rod, radial lengths H1, H2 perpendicular to an axial center of a through-hole in each of cross-sectional forms in a pair of the broken portions are set longer than widths B1, B2 in the axial direction of the through-hole. Then, an insertion hole 8 for inserting the fastening member for fastening the rod section and the cap section is formed. Further, in an inner-diameter portion in the vicinity of the insertion hole 8, a width enlarged portions E1, E2 are formed in which the widths B1, B2 in the axial direction of the through-hole are set larger than a large-diameter portion made larger than the inner-diameter portion.
