A method for producing an electrical connection between an electrical conductor, which includes a plurality of individual wires, and a contact element. The electrical conductor is arranged in a contact portion of the contact element, and the contact portion and the electrical conductor are subsequently pressed together so that the contact portion surrounds the electrical conductor. A a plurality of mutually spaced elongate welded connections between the contact portion and the electrical conductor are produced by laser irradiation of the contact portion, or by laser irradiation of the electrical conductor through an opening in the contact portion. The elongate welded connections extend in an irradiation direction from an irradiated region of the contact portion, or from an irradiated region of the electrical conductor, through an entire cross-section of the pressed electrical conductor to a region of the contact portion opposite to the irradiated region, such that the electrical conductor is connected to this area of the contact portion; and the irradiated regions are arranged in the form of a grid.

A hot wind is blown to a land and a lead from the underside of a printed board, to perform preheating. At the start of preheating or after start of preheating, a laser beam is applied to a soldering point, and meanwhile, wire solder is fed to a position contacting with the soldering point. The fed wire solder is melted by the laser beam. After soldering is finished, feeding of the wire solder is stopped. Application of the laser beam is stopped, to solidify the melted solder.
