PROBLEM TO BE SOLVED: To provide an antimicrobial agent comprising an oil obtained by separation/recovery using a cheap separation method from a condensate obtained by cooling the exhaust discharged when drying a Japanese cedar lumber. SOLUTION: This antimicrobial agent uses an oil obtained by either one of a method in which the condensate obtained by drying a Japanese cedar lumber, favorably "obisugi" Japanese cedar lumber, Cryptomeria japonica, is left at rest and the supernatant oil is decanted, a method in which solvent extraction is used, or a method in which the condensate is adsorbed in an adsorber column made of a synthetic resin and is desorbed later.
