PURPOSE: To obtain a nonsticky chewing gum, containing collagen in a gum base and excellent in preventing effects on sticking to not only tooth or denture but also flooring, etc.

CONSTITUTION: This gum contains preferably 2-18wt.%, more preferably 15-18 wt.% collagen in a chewing gum base. Besides the collagen, e.g. an elastic body, a wax or an inorganic substance may be used. When the blending ratio of the elastic body having a high molecular weight and a wax having a high melting point is especially raised, the resultant chewing gum is more preferred from the viewpoint of preventing effects on the sticking. The nonsticky effects are further preferred if a propylene glycol ester of a fatty acid represented by the formula (R is an aliphatic group) is blended.
