The invention relates to a high-voltage power distributor (2) which is designed to keep the need for high-voltage supply lines (22A, 22B) as low as possible for an electric or hybrid vehicle having an electric-motor driving motor, which high-voltage power distributor (2) comprises a distributor housing (4) having a connection space (18). At least one incoming supply line (22A) and two outgoing supply lines (22B), which are connected to each other, are introduced into the connection space (18). The distributor housing (4) has a two-part construction, which comprises a conductive inner housing (6) and an insulating outer housing (8). Each respective shield (28) of a respective supply line (22A, 22B) is connected to the inner housing (6) in an electrically conductive manner. Thus, a mechanically robust design is enabled together with good EMC shielding in the connection region of the supply lines (22A, 22B), and furthermore reliable sealing with respect to the environment is enabled.
