To provide a spiral type gas-liquid contact membrane element which obviates the occurrence of the degradation in the concentration of a gaseous solution and the intrusion of air bubbles into the gaseous solution by rapidly discharging the condensed water in a gas side flow passage and a spiral type gasliquid contact membrane module.

Two sheets of gas side flow passage materials are disposed in channel parts along the flow direction of gaseous ozone and are arranged in spiral type membrane elements 10 in such a manner that the channel parts face each other. The gaseous ozone is supplied from a gas inlet 11a into a gas supply pipe 11, passes the spiral gas side flow passages 18 from supply holes 11b and is discharged outside from a gas outlet 7. The condensed water in the gas side flow passages 18 flows together with the gaseous ozone along the channel parts of the gas side flow passage materials and is discharged outside from the gas outlet 7.
