    摘要: An electroless gold plating solution is provided that contains no cyanide compound as a source of gold and that contains a decomposition inhibitor represented by general formula (1), provided that, in a case in which the solution contains a gold complex of sulfite and the decomposition inhibitor is cytosine, the pH 6.0 or less is excluded. In the formula, R1 to R4 denote hydrogen atom(s), alkyl group(s) having 1 to 10 carbon atom(s), which may have substituent(s), aryl group(s) having 6 to 10 carbon atoms, which may have substituent(s), alkoxy group(s) having 1 to 10 carbon atom(s), which may have substituent(s), amino group(s) (—NH2), hydroxyl group(s) (—OH), ═O, or halogen atom(s), R2 and R3 or R3 and R4 may crosslink with each other and form a saturated or unsaturated ring and the saturated or unsaturated ring may include oxygen, sulfur or nitrogen atom(s), each of the above-mentioned substituents may be a halogen atom or a cyano group, and may be a single bond or a double bond.
