Document Type and Number:
WIPO Patent Application WO/2018/155418
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a multi-layer wiring substrate that enables suppressing inter-layer misalignment, and restraining transmission loss of an electric signal by using an adhesive layer having a superior peel strength when a fluorine resin substrate is used. Provided is a multi-layer wiring substrate 1 which comprises: a fluorine resin substrate 30 having a conductor pattern 20 formed at least on one surface thereof; and an adhesive layer 10 for adhering the fluorine resin substrate 30, wherein the adhesive layer 10 contains a cured product of a thermosetting resin, and has a fracture elongation of 20-300%.
