PROBLEM TO BE SOLVED: To obtain a microbicidal composition having a high microbicidal power, capable of maintaining the microbicidal power for a long period, having good durability against washing, and useful for producing microbicidal fibers or fiber products by adding a cationic microbicidal compound, an alkyl sulfate ester, etc. SOLUTION: This microbicidal composition contains (A) a cationic microbicidal compound, preferably an alkyldimethylbenzylammonium salt of the formula (R is a 10-16C alkyl; X- is an anion) (for example, dodecyldimethylbenzylammonium chloride) and (B) an alkyl sulfate ester salt or an alkylbenzene sulfonate salt (for example, sodium dodecylbenzenesulfonate, sodium lauryl sulfate) in a molar ratio of preferably 1:0.1 to 1:2, more preferably 1:0.2 to 1:1. The component A is added in an amount of preferably 0.1-50 wt.%, more preferably 1-20 wt.%.
