A laminated body comprises a thermally conductive sheet, a protective sheet, an auxiliary sheet, a carrier sheet and a coating sheet. The thermally conductive sheet comprises a main sheet body and an adhesive layer. The coefficient of static friction of the main sheet body is 1.0 or lower. The adhesive layer has high adhesiveness in comparison with the main sheet body, and has an outer shape smaller than that of the main sheet body. The protective sheet is formed having an outer shape larger than that of the adhesive layer, and provided with a cutting line extending toward the adhesive layer from the peripheral portion of the protective sheet so that the protective sheet can be cut along the cutting line.
