Abstract
A membrane circuit board includes a first substrate, a second substrate, a space layer and a conductive adhesive. The first substrate includes a plurality of first butting circuits and at least one first transmission circuit. The first transmission circuit is connected to one of the first butting circuits. The second substrate includes a plurality of second butting circuits, each corresponding to one of the first butting circuits. The space layer is disposed between the first substrate and the second substrate. The space layer includes a butting opening and at least one first stress weakening portion. One end of the first stress weakening portion is connected to the butting opening, and the first stress weakening portion corresponds to the first transmission circuit. The conductive adhesive is disposed within the butting opening and is in contact with both the first butting circuits and the second butting circuits.
