The present invention relates to a sanitary product 100 comprising a back sheet 102, having an outer surface 130 and an inner surface 120, a core 104 having a core back side 104A and a front sheet 106 joined with a joining periphery 108 in a sandwich structure with the core 104 fully comprised within the joining periphery 108. The core 104 is arranged between the back sheet 102 and the front sheet 106 with the inner surface 120 of the back sheet 102 facing the core back side 104A. The sanitary product 100 is configured with a long direction 110, a perpendicular short direction 112 and a product periphery 114, and comprises a printed circuit 122, which comprises a connector 124 configured with a connector width 126 and a sensor 128 for humidity detection, which printed circuit 122 is comprised on a sheet surface facing the core back side 104A. The sanitary product 100 further comprises a stiffener 132 arranged on the outer surface 130 of the back sheet 102 opposite the connector 124, two through-going incisions 140 in the long direction 110 and an intersecting cut 144 intersecting the two through-going incisions 140. The joining periphery 108 encircles a smaller area than the product periphery 114 and is comprised within the product periphery 114, and the connector 124, the two through-going incisions 140 and the intersecting cut 144 are outside the joining periphery 108. The invention relates to the sanitary product 100, a fabrication line 300 therefore, a method 400 for producing thereof and a semi-manufactured sanitary product 200 therefore.La présente invention concerne un produit sanitaire 100 comprenant une feuille arrière 102, ayant une surface externe 130 et une surface interne 120, un noyau 104 ayant un côté arrière de noyau 104A et une feuille avant 106 jointe à une périphérie de jonction 108 dans une structure en sandwich, le noyau 104 étant entièrement compris dans la périphérie de jonction 108.
