Claim:
1. A crimp terminal comprising: a terminal metal fitting including a terminal connecting portion to be electrically connected to a counterpart terminal, an electric wire connecting portion to be electrically connected to an end of an electric wire placed on an inner wall face side by crimping processing, and a coupling portion coupling the terminal connecting portion and the electric wire connecting portion, the electric wire connecting portion being sectioned into a bottom portion on which the end of the electric wire is placed during the crimping processing, an inner first barrel piece that is caused to extend from one end of the bottom portion to be wound around the end of the electric wire, and an outer second barrel piece that is caused to extend from another end of the bottom portion longer than the first barrel piece does and to be wound around the end of the electric wire and the first barrel piece, and the electric wire connecting portion being sectioned into a core wire crimp portion to be crimped onto a distal-end core wire of the electric wire, a sheath crimp portion to be crimped on a sheath of the electric wire, and a coupling crimp portion coupling the core wire crimp portion and the sheath crimp portion and to be crimped onto the end of the electric wire; and a water stop member that forms a first water stop area that is affixed to the inner wall face of the electric wire connecting portion before performing the crimping processing and suppresses entry of water from a gap between an outer wall face of the first barrel piece and the inner wall face of the second barrel piece to a gap between the electric wire connecting portion and the core wire after completion of the crimping processing, a second water stop area that suppresses entry of water from the terminal connecting portion side of a distal end position of the core wire to the gap between the electric wire connecting portion and the core wire, and a third water stop area that suppresses entry of water from a gap between the inner wall face of the sheath crimp portion and the sheath to the gap between the electric wire connecting portion and the core wire, wherein the inner wall face of a distal end in an extension direction of the first barrel piece of the sheath crimp portion includes a tapered face that reduces a plate thickness of the first barrel piece from the bottom portion side toward an end face side of the distal end, and a part of the third water stop area is connected among the end face side of the distal end of the first barrel piece, the inner wall face side, and the outer wall face side.
