Method for producing millimeter-wave permeable resin member having metal film formed on resin substrate and millimeter wave permeable resin member

摘要

PROBLEM TO BE SOLVED: To provide a production method of a millimeter wave-transmissible resin member having lower production cost than the case for forming a metallic film by using indium, and further having jointly high millimeter wave transmissivity and sufficient metallic sheen.SOLUTION: A production method of a millimeter wave-transmissible resin member has an A-layer formation step for forming an A-layer comprising tin or a tin alloy by a sputtering method or a vacuum deposition method on one surface of a substrate comprising a transparent resin, and a B-layer formation step for forming a B-layer comprising aluminum or an aluminum alloy layer on a surface on the opposite side to the surface having a contact with the substrate of the A-layer.SELECTED DRAWING: None
