A cyanopyrrolidine derivative represented by Formula (1): [wherein R<1 >is a halogen atom, a hydroxyl group, an alkoxy group having 1 to 5 carbon atoms or an alkyl group having 1 to 5 carbon atoms, R<2 >is a hydrogen atom, a halogen atom, a hydroxyl group, an alkoxy group having 1 to 5 carbon atoms or an alkyl group having 1 to 5 carbon atoms, or R<1 >and R<2 >together form an oxo, a hydroxyimino group, an alkoxyimino group having 1 to 5 carbon atoms or an alkylidene group having 1 to 5 carbon atoms, R<3 >and R<4 >are each a hydrogen atom, a halogen atom, a hydroxyl group, an alkoxy group having 1 to 5 carbon atoms or an alkyl group having 1 to 5 carbon atoms, or R<3 >and R<4 >together form an oxo, a hydroxyimino group, an alkoxyimino group having 1 to 5 carbon atoms or an alkylidene group having 1 to 5 carbon atoms, X is an oxygen atom or a sulfur atom, Y is -CR<5>R<6>- (wherein R<5 >and R<6 >are the same or different, and are each a hydrogen atom, a halogen atom, an optionally substituted alkyl group having 1 to 10 carbon atoms or an optionally substituted alkenyl group having 2 to 10 carbon atoms), or -CR<7>R<8>-CR<9>R<10>- (wherein R<7>, R<8>, R<9 >and R<10 >are the same or different, and each a hydrogen atom, a halogen atom or an optionally substituted alkyl group having 1 to 10 carbon atoms, or R<7 >and R<9 >together with the carbon atom to which they are attached form an optionally substituted cycloalkyl group having 3 to 8 carbon atoms, an optionally substituted cycloalkenyl group having 4 to 8 carbon atoms, an optionally substituted bicycloalkyl group having 5 to 10 carbon atoms, or an optionally substituted bicycloalkenyl group having 5 to 10 carbon atoms) and Z is a hydrogen atom or an optionally substituted alkyl group having 1 to 10 carbon atoms, or Y and Z together with the nitrogen atom to which they are attached form an optionally substituted cyclic amino group having 2 to 10 carbon atoms], or a pharmaceutically acceptable salt thereof.
