PURPOSE:To carry out uniform and high quality plating at high speed when the broad surface of a beltlike body is plated by jetting a plating soln., by piercing many jetting holes in a nozzle for jetting the plating soln. and by rotating the jetting holes. CONSTITUTION:When a broad and long-sized beltlike body 4 such as stock for a lead frame is partially plated to form a striped pattern, the body 4 is masked with a masking tape 2 for partials plating, immersed in a plating soln. 1 in a plating tank 3 and travelled in the horizontal direction. A pipe-shaped nozzle 6 having many jetting holes 9 is placed near the surface 8 of the body 4 to be plated and the holes 9 are rotated in the direction of arrows 10 to produce jets 5 of the plating soln. 1. The plating soln. 1 is stirred on the parts of the surface 8 to be plated in a nearly uniform state, so layers having similar characteristics are formed to a nearly uniform thickness by plating.
