A conductive module includes spaced conductive layers and connecting lines. Adjacent conductive layers are electrically connected by one connecting line. Each connecting line includes a contact portion and an extending portion, the contact portion is electrically connected to one conductive layer and the extending portion. The extending portion is very stretchable in effective length to render the conductive module stretchable and deformable. A projection of the contact portion on a plane where the extending portion extends is a square, a width of the extending portion is equal to a side length of the contact portion.
