An electric connector including a male connector and a female connector,

• said male connector including a cylindrical main portion, and a male contact terminal formed at said main portion,
• said female connector including a hole into which said cylindrical main portion is fit, and a female contact terminal formed at said hole for making electrical contact with said male contact terminal when said main portion is fit into said hole,
• one of said male connector and said female connector including a guide shaft axially extending in a direction in which said male connector is fit into said female connector,
• the other of said male connector and said female connector including a guide hole for allowing said guide shaft to be inserted thereinto to guide said guide shaft in said direction,
• one of said male contact terminal and said female contact terminal being comprised of at least one cylindrical first terminal arranged coaxially with said guide shaft, and the other of said male contact terminal and said female contact terminal being comprised of a second terminal arranged in correspondence to said cylindrical first terminal,
• said second terminal including a contact portion exposed outside for making contact with said cylindrical first terminal, and an embedded portion being embedded in the other of said male contact terminal and said female contact terminal,
• said embedded portion being outwardly bent at opposite ends thereof to thereby define curved portions, said curved portions being inserted into a housing of said electric connector,
• said cylindrical main portion of said male connector including a first portion and a second portion adjacent to said first portion and located remote from a distal end of said main portion,
• said first portion being cylindrical,
• said second portion including a main portion projection extending outwardly from a surface of said second portion,
• said female connector including a stopper for engaging said main portion projection to prevent said male connector from rotating about an axis thereof, and
• said main portion projection having a diameter smaller than a diameter of said first portion.
