The present disclosure provides a bio-implantable device and a method for manufacturing the same, the bio-implantable device comprising: a substrate section made of a polymer； a wi re section formed on a surface of the substrate section； at le ast one micro wire array comprising a cover section made of a polymer and attached to the surface of the substrate section, on which the wire section is formed, so as to protect the wire section and to expose at least one end of the wire section, t hereby forming a pad section； a functioning section electrica lly connected to the pad section； and at least one package com prising an encapsulating section made of a polymer so as to ab ut the functioning section and the pad section with no space t herebetween, thereby protecting the same, the encapsulating s ection extending up to a part adjacent to the substrate sectio n and to the pad section of the cover section and being attach ed thereto, the package being connected to an end of a corresp onding micro wire array.
