BIOLOGICAL INFORMATION MEASURING APPARATUS AND MANUFACTURING METHOD THEREOF

摘要

A biological information measuring apparatus and a manufacturing method thereof are provided to secure stability and reliability in collecting a blood sample by using a high rigidity minute needle coated with metal. A biological information measuring apparatus includes a minute needle(10) as a blood sampler. The minute needle includes non-metal needle structures, penetration units, an attachment reinforcing layer, and a non-oxidizing metal layer. The non-metal needle structures are arrayed on a substrate and have pointed parts respectively. Each of the penetration units vertically passes through the substrate from a part of the needle structure. The attachment reinforcing layer is formed on the substrate including surfaces of the needle structures. The non-oxidizing metal layer is formed on the entire upper surface of the attachment reinforcing layer.
