The present disclosure provides a crimp terminal in which a core wire is kept from coming loose. The crimp terminal 14 includes a plate-like crimp portion 15 that is to be crimped to a core wire of an electric wire by being deformed so as to wrap around the core wire, and a protruding portion 16 that protrudes from the inner surface of the crimp portion 15. A groove 21 that extends along a direction that intersects the extending direction of the core wire is provided in the protruding portion 16.
