The present invention relates to the technical field of heating equipment, and particularly to a steam generator, comprising a shell and a heater fixed inside the shell, a gasification chamber for generating steam being formed between the heater and the shell, the gasification chamber being provided with a water inlet and a steam outlet. The gasification chamber comprises stepped or labyrinthic steam passages. As the gasification chamber inside the steam generator provided by the present invention comprises stepped or labyrinthic steam passages, heat both inside and outside the heating element is fully utilized, the steam passage is lengthened, and both the pressure and temperature are increased; consequently, high-temperature steam may be provided. Moreover, the time for ejecting steam is greatly shortened just several seconds from feeding water to ejecting steam, with high heat utilization efficiency. Moreover, the steam generator is small in size.
