Abstract
A connecting rod includes a rod main body, a small end located at one end of the rod main body and a big end located at another end of the rod main body, the big end including a curved section which is curved so as to become narrower toward the rod main body. The big end is formed of a metal material whose composition is different from that of the rod main body, and is bonded to the rod main body. A joint between the big end and the rod main body is located closer to the small end than is an end of the curved section facing the rod main body.
