The present invention relates to a continuous production method for silicon tetrafluoride (SiF4) using silica (SiO2) and hydrogen fluoride (HF), and, more specifically, relates to a continuous production method for silicon tetrafluoride, wherein silica and hydrogen fluoride (HF) are reacted by filling a bed reactor with crystalline or amorphous silica in the solid state and blowing hydrogen fluoride gas directly therein, such that it is possible to continuously produce silicon tetrafluoride in a high yield, and it is possible to use diverse forms of silica as raw materials and hence it is possible to ensure relatively economic operation.
