<P>PROBLEM TO BE SOLVED: To provide a unit for detecting concentration in liquid capable of accurate measurement without increasing costs and deteriorating durability after a long use by preventing drops and bubbles from adhering, and to provide a measuring apparatus of concentration in liquid using the unit for detecting concentration in liquid, and the measuring apparatus of concentration in liquid. <P>SOLUTION: A unit for detecting concentration in liquid comprises: a substrate, having a group of electrodes 4 including a working electrode 4a that reacts corresponding to the concentration of a specific constituent in liquid and a wiring pattern from the group of electrodes 4; and an external body 9 having an opening 8 that opens greater than the group of electrodes 4. When the group of electrodes 4 of the sensor section of the concentration in liquid in which the substrate and the external body 9 are adjacent each other while the group of electrodes 4 are arranged in the opening 8 are set to a lower side, a wiring pattern from the working electrode 4a is arranged in a range separated from the upper section of the opening 8 at least by 0.2 mm. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
