The present invention provides a urea derivative or a salt thereof, which is useful as a therapeutic agent for thrombosis. The derivative is represented by Formula (I):
[Chemical formula I]
wherein Cy is an aromatic hydrocarbon group which may be substituted or an aromatic heterocyclic group which may be substituted; R1 is a hydrogen atom or a hydrocarbon group which may be substituted; V is -C(O)-, -S(O)-, or -S(O)2-; W is -N(R2)-, -O-, or a bond (wherein R2 is a hydrogen atom or a hydrocarbon group which may be substituted); X is alkylene which may be substituted; Y is -C(O)-, -S(O)-, or -S(O)2-; Z is a bond, a chain hydrocarbon group which may be substituted, or -N=; ring A is a non-aromatic nitrogen-containing heterocyclic ring which may be substituted; ring B is a nitrogen-containing heterocyclic ring which may be substituted; and
