Abstract: A method of producing a laminate according to an embodiment of the present invention includes applying an application liquid containing a polyvinyl alcohol-based resin to one side of a resin substrate, followed by drying of the application liquid to form a polyvinyl alcohol-based resin layer. The method includes: passing the application liquid before the application through a depth-type filter having a filtration accuracy of from 50 μm to 100 μm; and fluctuating a pressure applied to the application liquid supplied to the depth-type filter to remove air bubbles in the filter.
