摘要： A laminated sheet having electromagnetic wave shielding effects and a manufacturing method therefor are provided wherein the laminated sheet is transparent, has electromagnetic wave shielding effects and is easily manufactured, moreover, an earthing terminal can be easily connected to the laminated sheet, and post-processing such as ultrasonic adhesion and the like can be easily conducted on the laminated sheet. In the manufacturing method, a conductive mesh-like sheet and a thermoplastic resin sheet are positioned between two molding plates and heated, these sheets are integrally laminated by means of the application of pressure between molding plates. In addition, as the above-mentioned thermoplastic resin sheet, a thermoplastic resin sheet having at least one resin layer which has a thickness which is two times or greater than the thickness of the conductive mesh-like sheet and which has uniform thermal properties is used. In the laminated sheet, at least one side of the conductive mesh-like sheet is imbedded and fixed within the resin layer. It is preferable for the laminated sheet to have exposed portions of conductive mesh formed into a section in which exposed portions of conductive mesh are exposed above the resin layer, on one side.
摘要翻译：提供一种具有电磁波屏蔽效果的层压片及其制造方法，其中层压片是透明的，具有电磁波屏蔽效应并且易于制造，此外，接地端子可以容易地连接到层叠片材，并且后处理例如超声波粘合等可以容易地在层叠片材上进行。在制造方法中，将导电网状片和热塑性树脂片定位在两个成型板之间并加热，这些片通过在成型板之间施加压力而一体地层压。另外，作为上述热塑性树脂片，使用具有至少一层树脂层的热塑性树脂片，该树脂层的厚度是导电网状片材的厚度的两倍或更多，并且具有均匀的热性能。在层压片中，将导电网状片材的至少一面嵌入并固定在树脂层内。优选地，层叠片材具有形成为导电网的露出部分暴露在树脂层上方的一侧的导电网的露出部分。
