Fluorine resin film and laminated body, and the manufacturing method of a hot press laminated body

摘要

Providing a method of producing a fluororesin film or a fluororesin laminate having excellent heat resistance and excellent interlayer adhesion to a lamination object such as a prepreg, a heat press laminate using the film or a laminate, and a method of manufacturing a printed board The purpose. A fluorine resin film containing a fluorine resin having a melting point of 260 ° C. to 380 ° C. and having an arithmetic mean roughness Ra of at least 1 μm ² of at least one surface in the thickness direction measured by an atomic force microscope. When it has layer B (12) which consists of layer A (10) containing the said fluororesin and another base material, and measures inside 1 micrometer ² of 2nd surface 10b of layer A (10) by atomic force microscope The laminated body (1) whose arithmetic mean roughness Ra of is 3.0 nm or more.
