<p><P>PROBLEM TO BE SOLVED: To provide an insulating sheet and a laminated structure high in handleability at a non-cured state, capable of obtaining a cured object with high heat resistance and capable of restraining a warp of a laminated object laminated on the cured object. <P>SOLUTION: The insulating sheet contains a polymer with a diphenylene sulfone group, a curing compound with an epoxy group or an oxetane group, a curing agent and a filler. The laminated structure 1 is provided with a substrate 2 having a first conductive layer 2b at least on one of its faces and either a through-hole or a concave part on one of the faces, insulating layers 3, 4 laminated on one or both faces of the substrate 2, and second conductive layers 5, 8 laminated on a face opposite to the face of the substrate 2 laminated with the insulating layers 3, 4 or a circuit board. The insulating layers 3, 4 are formed by curing the insulating sheet. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
