Crimp terminal and electric wire with crimp terminal

A crimp terminal includes an F-type crimp portion and a C-type crimp portion. The F-type crimp portion has first and second barrel tabs, preferably with an identical length, for crimping a tip end of a complex stranded wire. The F-type crimp portion is adapted to have distal ends of the first and second barrel tabs put together and pushed into the tip end of the complex stranded wire to be crimped. The C-type crimp portion has a third barrel tab for crimping the complex stranded wire. The third barrel tab is wound in a C-form on an outer periphery of the complex stranded wire to be crimped. The arrangement provides a crimp terminal and an electric wire with crimp terminal, that prevents or reduces increases in retained resistance at a crimp portion, and can also prevent an electric wire from slipping out of a crimp terminal.
