The present invention relates to a urea derivative or a pharmacologically acceptable salt thereof having an excellent DGAT inhibitory effect. A urea derivative having the formula:n n[wherein R 1 is a C 6 -C 10 aryl group which may be independently mono- to pentasubstituted by a group selected from Substituent Group a or others; R 2 is a C 6 -C 10 aryl group which may be independently mono- to pentasubstituted by a group selected from Substituent Group a or others; E is a group having the formula (II) or the formula (III) (wherein R 3 is a hydrogen atom or others; R 4 and R 5 , which are the same or different, are a hydrogen atom or others; X and U, which are the same or different, are a group represented by the formula CH or others; m and n, which are the same or different, are 1 or another number) or others; and A is a group represented by the formula -NH-C(=O)- or others], or a pharmacologically acceptable salt thereof. |
