Abstract
In a method of spot-welding flat-type electrical conductors, sandwiched between insulators, to metal terminals, a portion of one insulator layer is removed from an end portion of a flat-type electrical conductor to expose the electrical conductors on one side. The end portion of the electrical conductors is put between two metal plates which is connected to form a metal terminal. A projection is formed on the metal plate which is disposed on the exposed conductor side such that it is in contact with the conductor before the conductor is spot-welded to the metal plates.
