Title:
RESIN MULTILAYER SUBSTRATE AND METHOD FOR PRODUCING RESIN MULTILAYER SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2020/203724
Kind Code:
A1
Abstract:
A resin multilayer substrate (101) comprises: a laminated body (10) formed by laminating a plurality of resin layers (11, 12); a first planar conductor (external conductor (41)) formed in the resin layer (12); and an interlayer-connecting conductor formed in the resin layer (12). The interlayer-connecting conductor includes a first interlayer-connecting conductor (V1) connected to the external conductor (41), and a second interlayer-connecting conductor (V2) bonded to the first interlayer-connecting conductor (V1) and to a planar conductor (31). The second interlayer-connecting conductor (V2) is made from a material different from the first interlayer-connecting conductor (V1). The second interlayer-connecting conductor (V2) includes, between a bonded portion of the first interlayer-connecting conductor (V1) and a bonded portion of the planar conductor (31), a constricted portion (CP) with a planar cross-sectional area smaller than the other portions.
