A membrane material lamination device and a membrane material laminating method using the same are provided. The membrane material lamination device includes: two support structures, each support structure includes a support surface, the two support structures is capable of being in either a first state where the support surfaces are located in an identical plane or a second state where the support surfaces are located in different planes; a pressure application mechanism configured to be located at a first position when the two support structures are in the first state to support the membrane material through the support surfaces of the two support structures, and moved to a second position when the two support structures are in the second state to support the membrane material through the pressure application mechanism and a first support structure; a first driving mechanism; and a second driving mechanism.
