Abstract Bumps are formed by means of uniform plating in which air can be easily discharged. A plating device comprises: a plating tank 32; a holding jig 34 detachably attached to an object 35 to be plated, the holding jig 34 being connected with a cathode and electrically connected with the object 35 to be plated, the object 35 to be plated being dipped in a plating solution, by the holding jig 34, substantially vertically or obliquely to the surface of the plating solution in the plating tank so that the surface to be plated can be directed upward; a cylindrical body 39 made of insulating material arranged in the front of the object 35 to be plated held by the holding jig 34 while a short clearance is left between the cylindrical body 39 and the surface to be plated and an axial line of the cylindrical body 39 is substantially perpendicular to the surface to be plated; an anode plate 37 arranged in the cylindrical body 39 being opposed to the surface of the object 35 to be plated; and a nozzle 40 arranged in the cylindrical body 39 while it penetrates the anode plate 37 and the plating solution is jetted onto the surface to be plated from the nozzle end section located in the cylindrical body 39.
A plating device comprising: a plating tank; a holding jig detachably attached to an object to be plated, the holding jig being connected with a cathode and electrically connected with the object to be plated, the object to be plated being dipped in a plating solution by the holding jig substantially vertically or obliquely to the surface of the plating solution in the plating tank so that the surface to be plated can be directed upward; a cylindrical body made of an insulating material arranged in the front of the object to be plated held by the holding jig while a clearance is left between the cylindrical body and the surface to be plated and an axial line of the cylindrical body is substantially perpendicular to the surface to be plated; an anode plate arranged in the cylindrical body being opposed to the surface of the object to be plated; and a nozzle arranged in the cylindrical body while it penetrates the anode plate and the plating solution is jetted onto the surface to be plated from the nozzle end section located in the cylindrical body.
