A plurality of electronic wires are fixed by a mold part in a state arranged in at least two rows. The mold part has a first end face from which the electronic wires of a first row in the plurality of electronic wires protrude and a second end face from which the electronic wires of a second row in the plurality of electronic wires protrude. An angle of the first end face with respect to a direction of a central axis line of a multi-core cable differs from an angle of the second end face with respect to the direction of the central axis line. The electronic wires of the first row in the first end face protrude along a direction away from the electronic wires of the second row protruding from the second end face.
