PURPOSE:To provide a chip exchange type electrode capable of easily exchanging a liquid path of a reference electrode and an adsorbent at once and setting the distance between an inner electrode and a liquid path large without large- sizing the electrode. CONSTITUTION:Provided are an electrode body 4 forming an inner electrode containing room 8 for connecting by way of a slit type path 24 and a reference electrode chip containing room 10 in parallel, and a reference electrode exchange chip 26 wherein the base end side opening of a box 30 containing ion adsorbent 28 is blocked with net material 32 and a liquid path fixing part 42 is fixed at the tip side opening. In the reference electrode chip containing room 10 of the electrode body 4, the body 30 for the reference electrode exchange chip 26 is contained. At the tip side opening of the reference electrode chip containing room 10, the liquid path fixing part 42 of the reference electrode exchange chip 26 is fixed in liquid seal state and detachably. |
