Wiring pattern formation method, manufacturing method for multi layer wiring substrate, and electronic device

摘要

A wiring pattern formation method in which a wiring pattern is formed by arranging, in a region which is demarcated by a partition wall, liquid material which includes an electrically conductive material, including: arranging a resin material around the periphery of a region upon which the wiring pattern is to be formed; imparting liquid affinity to a demarcated region which has been demarcated by the resin material; narrowing down the demarcated region by flowing out the resin material towards and into the demarcated region; and forming the partition wall by curing the resin material.
