A flickering candle is provided, mainly including: a candle main body, a base and a pattern unit. The candle main body is a hollow light-transmittable shell, with an outer surface, an inner surface, a top and a bottom, both connecting the outer surface and the inner surface. The base is fixedly engaged to the bottom of the candle main body, and disposed with at least a light-emitting element. The pattern unit includes a light-transmittable first patter plate, overlappingly disposed on the inner surface of the candle main body. The first pattern plate has a predefined pattern and a light-guiding part contacting the light-emitting element. As such, the light-emitting element at the base can disperse the light source through the light-guiding part onto the first pattern plate so that the predefined pattern becomes more spectacular to enhance the esthetics.
