A gas-liquid dispersion device to be installed in a system in which a liquid flows forming a continuous phase and a gas flows upward includes a perforated plate which is so mounted as to interrupt a gas-liquid passage, in which a mixed phase of the gas and liquid is produced. A separated liquid-conducting channel extending from the perforated plate toward its gas inflow opening side is formed in such a way that a gas-liquid passage is divided into a liquid-conducting portion and a gas-dispersing portion. When the mixed phase of the gas and liquid is supplied to the gas-liquid dispersion device, a gas phase accumulates on the gas inflow opening side of the gas-liquid dispersion device and creates a gas pocket, whereby pulsation of gas and liquid flows can be prevented. As a result, the gas passes upward through individual through holes (excluding the liquid-conducting channel) made in the perforated plate while the liquid passes through the liquid-conducting channel in a stable manner.
