A gas mixture supplying method includes supplying plural kinds of gases through gas supply lines connected to a common pipeline and supplying a gas mixture of the plural kinds of gases from a gas outlet of the common pipeline into a region where the gas mixture is used through a gas mixture supply line. When a typical gas supplied in a gaseous state from a gas supply unit and a liquid source gas vaporized by heating a liquid source material supplied from a liquid source material supply unit by a vaporizing unit are supplied simultaneously, the liquid source gas is supplied from one of the gas supply lines provided at a position closer to the gas outlet than that for the typical gas, and the liquid source gas is supplied to a downstream side of a filter for removing particles in the typical gas. |
