A laminate for a biosensor is equipped with a pressure-sensitive adhesive layer for affixation to a living body surface, a substrate disposed on the upper surface of the pressure-sensitive adhesive layer, wiring disposed on the substrate, a probe disposed on the pressure-sensitive adhesive layer so that the lower surface of the probe is exposed, and a connection part that passes through at least the pressure-sensitive adhesive layer and connects the wiring and the probe. The connection part has a shape that traces at least part of the entire peripheral edge part of the probe and is equipped with a first contact part that contacts the peripheral edge part of the probe.本發明之生物體感測器用積層體具備:感壓接著層,其係用以貼附於生物體表面;基材,其配置於感壓接著層之上表面;配線,其配置於基材;探針,其係以下表面露出之方式配置於感壓接著層;及連接部,其至少通過感壓接著層內且將配線與探針加以連接。連接部具備具有沿著探針之整個周緣部之至少一部分之形狀且與探針之周緣部接觸之第1接觸部。2‧‧‧感壓接著層3‧‧‧基材4‧‧‧配線層5‧‧‧探針6‧‧‧連接部11‧‧‧接著開口部15‧‧‧基材開口部16A‧‧‧第1配線18‧‧‧探針構件18A‧‧‧周面22‧‧‧外側面23‧‧‧貫通口23A‧‧‧內表面52‧‧‧孔53‧‧‧桿部61‧‧‧第1接觸部62‧‧‧第2接觸部63‧‧‧連結部
