The variations of the light curve of VW Cephei is examined in terms of a spot model. A light curve which is assumed to be free from starspot effects is constructed from Kwee's (1966) observations, and is analyzed by the light-curve synthesis method. Kwee's individual light curves are then further analyzed assuming that starspots exist on the surface of the primary component. The analysis shows that starspots move on the stellar surface with decreasing longitude with an approximate period of two years. In the light curve, the distortion (depression) of the light moves forward towards the decreasing phase. This may indicate that the rotation of the primary component, or the average rotation over the regions where starspots are dominant, is a little faster (by about 0.04% in the period of rotation) than the synchronous rotation.
