PROBLEM TO BE SOLVED: To provide a plating treatment device which is capable of uniformly passing a plating liquid to an anode and work and is applicable to a cylinder block of multiple cylinders as well. SOLUTION: This plating treatment device 1 has an outlet side jig 3 loaded with the cylindrical work 17 on the top surface 8 thereof and internally formed to a hollow section 5, the cylindrical anode 10 disposed in such a manner that its top end 6 protrudes from the top surface 8 of the outlet side jig 3 in the hollow section 5 of the outlet side jig 3 and a plating liquid tank 15 connected via piping 12 and 13 to the anode 10 and the outlet side jig 3. When the cylindrical work 17 is placed on the top surface 8 of the outlet side jig 3 and the upper side anode 31 is arranged within the work 17, the diameter of the lower side anode 30 is formed smaller than the diameter of the upper side anode 31.
