Crimp terminal, connecting structure, manufacturing method of the crimp terminal, and laser welding method

A crimp terminal comprising:

• a crimp portion formed in a tubular shape with an electrically conductive substrate and configured to crimp join with an electric wire;
• and
• a sealing portion formed at one end of the crimp portion and seals against the electric wire to be crimp joined to the crimp portion,
• at the sealing portion, an overlapped portion at which the substrate is bent and overlapped and joined, and in the overlapped portion, an end portion of the crimp portion formed in the tubular shape is squeezed,
• a joining trajectory is formed at the sealing portion from a position adjacent to one side portion of the crimp terminal to a position adjacent to another side portion of the crimp terminal in a widthwise direction of the crimp terminal, and a distance from each of the adjacent positions to the respective side portion of the crimp terminal is less than a sheet thickness of the substrate,
• the joining trajectory joins a top part of the overlapped portion to a bottom part of the overlapped portion, and
• one end of the joining trajectory is at a position that is deviated on a side opposite of the crimp portion with respect to the sealing portion.
