PROBLEM TO BE SOLVED: To develop a plating bath where, at the time of applying barrel plating to compact or low specific gravity parts, a nickel film can be uniformly formed thereon. SOLUTION: At the time when barrel plating is performed in such a manner that an oligo-molecular specific compound of fatty alcohols or ethers in which ethylene oxide or propylene oxide unit is repeated by 1 to 4 pieces, and having hydrogen or C<SB>1</SB>to C<SB>4</SB>alkyl radicals or C<SB>1</SB>to C<SB>2</SB>alkyl radicals on both the ends such as 2-methoxy ethanol, diethylene glycol monomethyl ether, dipropylene glycol and 1,2-dimethoxy ethane on both the ends is added to a nickel plating bath, wettability can be improved even to electronic parts largely including compact or low specific gravity parts floating in a plating bath, and the nickel plating film can be uniformly formed thereon.
