Provided are a crimp terminal, a pressure-bonding connection structural body and a method of manufacturing a pressure-bonding connection structural body by which the generation of pressure-bonding cracks can be avoided, and the pressure-bonding resistance can be made stable. A barrel portion 200 which allows the pressure-bonding connection of an aluminum core wire 101 exposed on a distal end of an insulated wire 100 covered with an insulating cover 102 is formed into a cylindrical shape by bending barrel portion corresponding portions of a terminal base material in a terminal developed state about a terminal axis. In abutting end portions 230a where the barrel portion corresponding portions abut each other, a welded part 230b which welds the end portions 230a is formed along a long length direction X of the insulated wire 100. The welded part 230b is formed on an upper surface concave portion 234a and a projecting portion 234T where an amount of plastic deformation of a conductor pressure-bonding section 232 generated along with the pressure-bonding of the conductor pressure-bonding section 232 becomes larger compared to other portions in a circumferential direction of the conductor pressure-bonding section 232. |
