The present invention provides an oily lip cosmetic that does not cause stringing and maintains a smooth feel. The polymer contains a polymer having one or more associative groups selected from an amide group, a carboxyl group, a hydroxyl group and a sulfo group and having a weight average molecular weight of 100,000 to 1,000,000 at a shear rate of 200 s −1 . An oily lip cosmetic in which the measured value of the first normal stress difference N1 is 200 Pa <N1 <1000 Pa, and does not show a peak time dependency when stress growth measurement is performed at 300 s −1 .
