To provide a laminate adapted to be used as a material of a resin bag needing moistureproofness and having excellent moistureproofness and strength and its molding machine.

The laminate manufacturing apparatus manufactures the laminate obtained by passing a resin film melted and dropped from a T-die and base material between a cooling roll and a pressing roll 2, continuously or intermittently forms a plurality of grooves 21 becoming an uneven shape at least at one side edge 22 in an oblique direction with respect to a shaft core direction of the roll 2 on an outer periphery of the roll 2 and forms it along a rotating direction or shaft core direction of the roll 2 in a direction of the unevenness. In the laminate, the resin film is covered and adhered at a portion corresponding to a portion of the grooves 21 of the roll 2 with the base material, and impregnated and adhered at a portion corresponding to a part except the grooves 21 with the base material.
