Wiring element, power distributor, and vehicle battery

The wiring element (10) has a circuit board (100) made of material with electrical conductivity. The board holds a connection element (50) and conductors (110) made of another material with electrical conductivity. The connection element is arranged in a contact area (20) of the board, which engages a partial surface of the board and is fixed at two sides of a surface of the board by a slot (30). The contact area is connected with a bar (40) that is separated from the board surface by the slot. The conductors are guided into the bar.
