摘要： A highly thermal-conductive and thermal-resistant electrically insulated coil with less outflow of a thermosetting resin composition can be produced, to provide a small-scale, light-weight rotating machine with high power. The thermosetting resin composition comprises (a) a polyfunctional epoxy resin containing three or more p-(2,3-epoxypropoxy) phenyl groups and a group represented by the Chemical formula 1; or an epoxy resin with a naphthalene backbone, represented by the Chemical formula 3, 4 or 5 or an epoxy resin with an anthracene backbone, such as diglycidyl ether of anthracene diol and triglycidyl ether of anthracene triol; (b) a bifunctional epoxy resin containing two p-(2,3-epoxypropoxy) phenyl groups; (c) an acid anhydride curing agent; and (d) a metal acetonate curing catalyst represented by the Chemical formula 2 at 0.1 to 5 parts by weight per 100 parts by weight of the epoxy resins.
