Abstract
A method of manufacturing a laminated substrate including an insulation substrate comprised of ceramic, and a front electrode formed on a front surface of the insulation substrate, a semiconductor element being mountable on a front surface of the front electrode, including forming the front electrode on the front surface of the insulation substrate, and before or after the forming the front electrode, applying laser processing to the front surface of the insulation substrate at an outer peripheral area of the front electrode to modify a conductive property of the front surface of the insulation substrate to have electrical conductivity.
