PROBLEM TO BE SOLVED: To obtain a new acrylonitrille compound capable of exhibiting an excellent pest control activity and useful as a new insecticide or a new germicide. SOLUTION: This acrylonitrile compound is represented by formula I (A is a 1-6C alkyl, a 2-6C alkenyl or the like; R1 is H, a 1-12C alkyl, a 2-12C alkenyl or the like; R2 is H, a 1-4C alkyl, a 2-4C alkoxyalkyl or the like; R3 is a 1-4C alkyl, a 2-4C alkenyl, a 1-4C haloalkyl or the like; R4 and R5 are each H, OH, SH, NH2, a halogen, a 1-4C alkyl or the like), e.g. 3-(1,4- dimethylpyrazol-5-yl)-3-hydroxy-2-(1-methyl-3-phenyl-1,2,4-triazol-5-y l)-acrylonitrile. The compound represented by formula I can be obtained by reacting a cyanomethyltriazole derivative represented by formula II with a carboxylic acid derivative represented by formula III (L1 is a leaving group) in the presence of a base and further reacting the resultant compound with a compound represented by formula IV (L2 is a leaving group).
