First claim
Opening claim text (preview).
1 . A plating solution comprising: (A) a soluble salt containing at least a stannous salt; (B) an acid selected from organic acid and inorganic acid or a salt of the acid; and (C) an additive, wherein the additive comprises a phosphonium salt with two or more of aromatic rings represented by a general formula (1) below, wherein, R 1 and R 2 in the formula (1) are identical or different, and are any one of a phenyl group, a hydrogen atom, CH 2 —O—CnH 2+1 , C n H 2n+1 , n being an integer from 1 to 5, Ph represents a phenyl group, and X represents a halogen. 2 . The plating solution according to claim 1 , wherein the additive further comprises a nonionic surfactant represented by a general formula (2) below, R 3 —Y 1 —Z—Y 2 —R 4 (2) and wherein, in the formula (2), R 3 and R 4 is the group represented by the formula (A) below, —(C n H 2n —O) m —H (A) and wherein, Y 1 and Y 2 represent a single bond or a group selected from —O—, —COO— and —CONH—; and Z represents a benzene ring or 2,2-diphenylpropane, and in the formula (A), n indicates 2 or 3 and m indicates an integer from 1 to 15. 3 . The plating solution according to claim 1 , wherein the additive further comprises a complexing agent and an antioxidant; or one of a complexing agent and an antioxidant. 4 . The plating solution according to claim 2 , wherein the additive further comprises a complexing agent and an antioxidant; or one of a complexing agent and an antioxidant.
