PROBLEM TO BE SOLVED: To provide a porous material which can properly control the oozing-out amount of a fluid. SOLUTION: This porous material 1 oozes out a fluid originating from a fluid supply source to the resin film side from an oozing-out orifice 12 through a flow path 11, when a continuous length resin film is manufactured. A plurality of board members 2, each with a channel part formed as a flow path 11, are laminated over each other and a resistance adjusting means which changes a flow resistance in the flow path 11, is furnished.
