A connecting rod (1) made of a titanium alloy is a split-type connecting rod which includes a rod main body (10), and a big end (30) located at an end of the rod main body (10), the big end (30) being fracture-split into a rod portion (33) which continues from the end of the rod main body (10) and a cap portion (34) which is coupled to the rod portion (33). The rod portion (33) and the cap portion (34) each have a fractured surface (F) on which rugged features are present. A difference in height between a highest portion and a lowest portion on each fractured surface (F) is about 230 µm or more.
