摘要：
A flexible substrate comprises a film, a first insulating resin layer on a front face of the film, a second insulating resin layer on a rear face of the film, a front-sided wiring pattern embedded in the first insulating resin layer, and a rear-sided wiring pattern embedded in the second insulating resin layer. A surface of the front-sided wiring pattern is flush with a surface of the first insulating resin layer, and a surface of the rear-sided wiring pattern is flush with a surface of the second insulating resin layer. A part of at least one of the front-sided wiring pattern and the rear-sided wiring pattern is dented toward a part of the other of the at least one of the front-sided wiring pattern and the rear-sided wiring pattern such that a portion of the front-sided wiring pattern and a portion of the rear-sided wiring pattern are jointed to each other to form a junction.
