  • ELECTROCHEMICAL SENSOR AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20090236224
    Abstract: It is an object of the present invention to provide an electrochemical sensor which can prevent occurrence of cracks at the welding portion between a support tube made of lead-free glass and a sensitive glass membrane or ceramics, and a method for manufacturing the same. The electrochemical sensor 100 has a configuration such that the sensitive glass membrane 2A is welded to the support tube 1 made of lead-free glass with a lead glass layer 3A between the sensitive glass membrane 2A and the support tube 1. According to the present invention, there is also provided the electrochemical sensor in which the ceramics 2B for a junction is welded to the support tube 1 made of lead-free glass with a lead glass layer 3B between the ceramics 2B and the support tube 1.
