An artificial candle lamp includes a candle body with a candlewick through hole. The candle body has an accommodating cavity communicated with the candlewick through hole. The upper part of the accommodating cavity has a shell below the candlewick through hole and the lower part thereof has a power source. A bracket is installed in the shell, an integrally formed candlewick member is erected on the bracket, a driving device is fixedly installed on the bracket, and a first light source is provided in the shell and powered by the power source. The candlewick member swings on the bracket under the combined action of its own gravity and the driving device. The candlewick member is integrally formed without additional assembly, thus eliminating the trouble of structural assembly of multiple components of the existing artificial candle lamp.
