Abstract

A multilayer conductive wire is formed of a plurality of conductive layers stacked upon each other, and has a slit shaped groove extending in the direction intersecting the direction of stress in at least one conductive layer. With the groove mating with a protrusion in another conductive layer or a protrusion in an insulating film layer, a sliding phenomenon between the layers due to the stress can be restrained, so that a multilayer conductive wire free from destruction due to the sliding phenomenon caused by the stress and without losing conductivity can be provided.
