PROBLEM TO BE SOLVED: To provide a cooler having cooling capacity varying section by section in the longitudinal direction, a mold which is bored from the surface and cooled by cooling capability varying in the depth direction of the hole, a resin multilayer film, T-shaped mold for sheet molding, film and method of producing a sheet.SOLUTION: A rod-like cooler is cooled by a coolant and divided so as to divide the axis of the rod-like body in the axial direction, and a coolant adjusted in cooling capacity section by section is supplied to and discharged from at least one end surface of the rod-like body. A mold in which the cooler is inserted into a hole pored from the surface, a resin film, a T-shaped mold for sheet molding, a film using the mold and a method of producing a sheet are also provide. |
