摘要： The present invention aims to provide a three-dimensionally shaped electrically insulating product having excellent formability in the process of three-dimensional formation and electrical insulation properties that are suppressed from deteriorating. Provided is a three-dimensionally shaped electrically insulating product formed by subjecting a sheet material having electrical insulation properties at least to a bending process, in which the sheet material includes a resin layer in the form of a sheet containing a thermoplastic resin having nitrogen or sulfur in a molecule and a protective layer in the form of a sheet disposed on each of both sides of the resin layer.

摘要： Provided are: an electrically insulating resin sheet for motors, which is used for achieving the insulation between coil wires or between a coil wire and an iron core in a motor, and which has high heat resistance, high electrical insulation performance and a high insulation breakdown voltage; and a process for producing the electrically insulating resin sheet. The electrically insulating resin sheet for motors, which is provided with a porous resin layer comprising a thermoplastic resin, is characterized in that the resin sheet has a relative permittivity of 2.0 or less at 1 GHz. It is preferred that the porous resin layer has an average cell diameter of 5.0 μm or less and contains cells in such an amount that the porosity is 30% or more.
