A substance detection sensor comprises an insulation layer (2) having flexibility, two electrodes (3A, 3B) so disposed on the insulation layer as to be opposite to each other at a space therebetween and connected to an electric resistance detector, and a conductive layer (4) which is so formed on the insulation layer as to span the two electrodes and to be electrically connected to the two electrodes. The swelling ratio of the conductive layer (4) is changed according to the type and/or the quantity of a specific substance.

A production method of a wired circuit board can prevent corrosion of a first thin metal film inwardly of a conductor layer, due to the forming of an undercut portion caused by a skirt portion of a plating resist. A first thin metal film is formed on an insulating base layer. A plating resist is formed in a reversal pattern to a wiring circuit pattern on the first thin metal film, and a conductor layer is formed in the wiring circuit pattern on the first thin metal film exposed from the plating resist. Thereafter, the plating resist is removed and, then, a second thin metal film is formed on the conductor layer and first thin metal film. Thereafter, the second thin metal film and then all portions of the first thin metal layer, except portions thereof where the conductor layer is formed, are removed.

A wired circuit forming board that can provide improved adhesion between an insulating layer and a conductive pattern and can also prevent delamination in a thin metal layer, a wired circuit board for which the same wired circuit forming board is used, and a thin metal layer forming method for forming the thin metal layer. The thin metal layer 2 is formed on the insulating base layer 1 by sputtering the first metal 35 and the second metal 36 in such a condition that a first metal diffusing region 37 for the first metal 35 to be diffused and a second metal diffusing region 38 for the second metal 36 to be diffused are overlapped with each other. This can allow formation of (i) a first unevenly-distributed metal portion 4 in which the first metal 35 is unevenly distributed and which is adjacent to the insulating base layer 1, (ii) a second unevenly-distributed metal portion 5 in which the second metal 36 is unevenly distributed and which is adjacent to the conductive pattern 6, and (iii) a metal coexisting portion 3 which is interposed between the first unevenly-distributed metal portion 4 and the second unevenly-distributed metal portion 5 and in which the first metal 35 and the second metal 36 are coexistent with each other in such a relation as to be continuously present in the thin metal layer 2 without defining any boundaries therebetween.
