Abstract: To provide a base fabric material having a pad member with a core and a manufacturing method thereof, the pad member with the core being capable of quickly and strongly joining the pad member, on which the core such as a cushion material is disposed, with beautiful finish in a state where the core is made to sufficiently project outward. The pad member having the core is joined to a one side surface of the base fabric material via an adhesive film, with its substantially entire area in thickness projecting, by performing thermocompression bonding by using a concave mold K, a convex mold HK, or the like having a hole or a groove made to match a shape or a thickness of the core. The adhesive film is made to have a mesh-like shape, or an adhesion preventing cloth is disposed and so on so as to ensure ventilation property.
