To improve the utilization efficiency of pure water for removing a contaminated gas without unnecessarily performing humidification while sufficiently ensuring the strength as a gas-liquid separating element.
In the gas-liquid separating element for separating and removing the contaminated gas G in air A' to be cleaned into a liquid (pure water W) by performing gas-liquid contact through a porous membrane 1, the flow in a boundary part of a liquid side where the flow rate is slow becomes better by attaching a protecting sheet 3 for reinforcement on an air side of the porous membrane 1, thereby the concentration gradient of the dissolved gas between the center part of the liquid flow and the vicinity part of the porous membrane 1 is released.
