Humidifier and a method for producing the same

A method for producing a humidifier that includes a plurality of moisture permeable humidifying membranes, and a plurality of gas separators each having a frame-shaped portion and one or two channels opened on opposite sides in a direction of lamination, through which at least one of a dry gas and a wet gas is caused to flow, wherein one of said humidifying membranes, one of said gas separators, another one of said humidifying membranes and another one of said gas separators are repeatedly laminated one over another in this order,

• said method comprising the steps of:
• cutting a resin sheet into a shape of that surface of the frame-shaped portion of each of said laminated gas separators which is in contact with a corresponding humidifying membrane;
• laminating said cut resin sheet on said corresponding humidifying membrane;
• and
• heating under pressure said resin sheet from its opposite sides thereby to fuse said resin sheet to fill a resin therein into said humidifying membranes.
