Abstract:
1. A flexible multilayer substrate comprising: a multilayer body including a plurality of laminated resin layers; wherein the multilayer body includes an innermost surface located on an inner side when the substrate is bent and an outermost surface located on an outer side when the substrate is bent; each of the plurality of resin layers includes a first main surface and a second main surface opposite to each other, and a skin layer is provided at the first main surface and is harder than other portions of the resin layer, and a conductor pattern is provided on the second main surface of the resin layer; the multilayer body includes a skin layer joint plane, which is a plane at which the first main surfaces of two of the resin layers adjacent to each other come into contact, at one location at a central portion in a thickness direction, and the first main surface and the second main surface of two of the adjacent resin layers come into contact at another location of the central portion in the thickness direction of the multilayer body; and the skin layer joint plane is arranged on a side closer to the innermost surface than a central plane in the thickness direction of the multilayer body.
