Method for manufacturing stretchable circuit board and stretchable circuit board

摘要

[Problem] Provided is a method for manufacturing a stretchable circuit board, which can facilitate positioning of an external terminal and a stretchable wiring, and increase manufacturing yield of a stretchable circuit board.;[Solving Mean] A stretchable circuit board is manufactured through: a step in which an external terminal 31 is formed on a main surface 33b located on one side of a film base 33; a step in which a stretchable wiring portion 55 is formed on a main surface 53a located on one side of a stretchable base 53; and a step in which the stretchable wiring portion 55 is positioned with the external terminal 31, and pressure and heat are applied to the film base 33 and the stretchable wiring portion 55 to join them, whereby the external terminal 31 and the stretchable wiring portion 55 are connected with each other.
