Abstract

PURPOSE:To separate a sensor from a lead wire and a connector so as to handle it by wrapping the connector contact of a connector for connecting the sensor and sensor contact part and providing insulating gel for insulating said contacts. CONSTITUTION:An electrode material 13 is formed in a band shape and a thin film on the surface of the electrode supporting base material 12 of the sensor 11 and an electrode material 14 is formed in a thin film all over the back surface of the electrode supporting base material 12. The insulating film 15 is formed on one surface of said base material 12. The insulating film 15 has two window parts and the electrode material 13 is exposed from these window parts to form a working electrode 16 and a contact part 17 respectively, so that all surface of the electrode material 14 becomes a reference electrode. The connector 1 is constituted of a connector main body 2, the contact 3 and the insulating gel 4, etc. In order to attach the connector 1 to the sensor 11, the trailing edge part 11a of the sensor 11 is inserted into the insertion hole 2b of the connector 1. The trailing edge 11a pushes away the insulating gel 4 and widens the contacts 3 and 3 to reach the inner wall of a hollow part 2a.

As a result, the benefits of miniaturization of the sensor cannot be fully utilized. Furthermore, although the above problem can be solved by attaching a connector directly to the sensor, it becomes difficult to insulate the connector portion.
