To provide an apparatus and method for gas replacement allowing for lowering the consumption of replacement gas, suppressing the amount of liquid spill from a container during gas replacement and obtaining the high efficiency of gas replacement, and reducing the variations of gas replacement distribution in a plane direction within a headspace.SOLUTION: An apparatus for gas replacement 10 has three or more nozzles 15, so that immediately before an opening 21a of a bottomed cylindrical container body 21 filled with a content 26 is covered by a lid 25 for closing the opening, replacement gas is laterally blown from the nozzles into a head space S between the opening of the container body and a top surface portion 26a of the filled content, thereby replacing the remaining gas within the head space by the replacement gas. In the gas replacement apparatus, the nozzles are arranged to blow replacement gas from...
