A terminal connection strip (100, 100A to 100C, 100Pa to 100Pc) comprising: a carrier formed in a strip shape; and a plurality of terminal fittings (110A to 110D, 110Pa to 110Pc) which project from at least one edge side of the carrier in a carrier width direction (Wc), wherein each of the terminal fittings (110A to 110D, 110Pa to 110Pc) includes a crimping section (130, 130A to 130D), each crimping section (130, 130A to 130D) is suitable for receiving at least a conductor tip of a wire, the conductor tip being a portion of the wire exposed by peeling off an insulating cover of the insulated wire on a distal end side, a proximal end side of the crimping section (130, 130A to 130D) and the carrier are connected to each other by way of a connection portion, wherein each crimping section (130, 130A to 130D) is formed from a plate-shaped base material, having barrel members extending from both sides of the base material in a terminal width direction (Wt), wherein the terminal width direction (Wt) is orthogonal to the carrier width direction (Wc), characterized in that the barrel members being then bent until the edge portions of the barrel members abut against each other to form a hollow cylindrical shape, both edge portions being then welded to each other to form a welded portion, and in that at least a proximal end side of the welded portion in the terminal long length direction (Lt) is formed at a place which is not disposed on the same plane as a carrier surface of the carrier, and in that the crimping section (130, 130A to 130D) is formed of a continuous integral body consisting of a wire crimping section and a sealing portion which are arranged toward a distal end side from a proximal end side, the sealing of the sealing portion being made by compressing a portion of the crimping portion on a distal end side from the wire crimping portion thereby resulting in each crimping section (130, 130A to 130D) having a water-blocking performance in a crimped state. a carrier formed in a strip shape; and a plurality of terminal fittings (110A to 110D, 110Pa to 110Pc) which project from at least one edge side of the carrier in a carrier width direction (Wc), wherein each of the terminal fittings (110A to 110D, 110Pa to 110Pc) includes a crimping section (130, 130A to 130D), each crimping section (130, 130A to 130D) is suitable for receiving at least a conductor tip of a wire, the conductor tip being a portion of the wire exposed by peeling off an insulating cover of the insulated wire on a distal end side, a proximal end side of the crimping section (130, 130A to 130D) and the carrier are connected to each other by way of a connection portion, wherein each crimping section (130, 130A to 130D) is formed from a plate-shaped base material, having barrel members extending from both sides of the base material in a terminal width direction (Wt), wherein the terminal width direction (Wt) is orthogonal to the carrier width direction (Wc), characterized in that the barrel members being then bent until the edge portions of the barrel members abut against each other to form a hollow cylindrical shape, both edge portions being then welded to each other to form a welded portion, and in that at least a proximal end side of the welded portion in the terminal long length direction (Lt) is formed at a place which is not disposed on the same plane as a carrier surface of the carrier, and in that the crimping section (130, 130A to 130D) is formed of a continuous integral body consisting of a wire crimping section and a sealing portion which are arranged toward a distal end side from a proximal end side, the sealing of the sealing portion being made by compressing a portion of the crimping portion on a distal end side from the wire crimping portion thereby resulting in each crimping section (130, 130A to 130D) having a water-blocking performance in a crimped state. wherein the terminal width direction (Wt) is orthogonal to the carrier width direction (Wc), characterized in that the barrel members being then bent until the edge portions of the barrel members abut against each other to form a hollow cylindrical shape, both edge portions being then welded to each other to form a welded portion, and in that at least a proximal end side of the welded portion in the terminal long length direction (Lt) is formed at a place which is not disposed on the same plane as a carrier surface of the carrier, and in that the crimping section (130, 130A to 130D) is formed of a continuous integral body consisting of a wire crimping section and a sealing portion which are arranged toward a distal end side from a proximal end side, the sealing of the sealing portion being made by compressing a portion of the crimping portion on a distal end side from the wire crimping portion thereby resulting in each crimping section (130, 130A to 130D) having a water-blocking performance in a crimped state.
