Document Type and Number:
WIPO Patent Application WO/2017/208747
Kind Code:
A1
Abstract:
The present invention comprises: preparing an aggregate substrate (10); and forming through-holes (20) and an electrode layer (400) in the aggregate substrate, wherein the electrode layer includes via electrodes respectively provided in the through-holes, back surface electrodes electrically connected to the via electrodes, a first wiring path and a second wiring path, the via electrodes have first and second via electrodes disposed in a first direction, the first wiring path includes a first extraction electrode provided in a first unit region and leading to a central part of a long side that touches a second unit region, and a second extraction electrode provided in the second unit region and leading to a central part of a long side that touches the first unit region, the first and second via electrodes are electrically insulated from via electrodes disposed in a second direction in a substrate disposition region, and by connecting the first extraction electrode and the second extraction electrode to each other by the central parts of the long sides, the back surface electrode electrically connected to the first via electrode and the back surface electrode electrically connected to the second via electrode are electrically connected to each other.
