TESTING APPARATUS OF SUBCUTANEOUS CONTAMINANT SUBSTANCE

PROBLEM TO BE SOLVED: To provide a biological power generation apparatus which has simple structure and which is inexpensive, disposable and has safety by avoiding using of an external power source as to a testing apparatus of a subcutaneous contaminant substance of an inverse iontophoresis type. SOLUTION: A metal Al or a metal having a normal electrode potential lower than that or a semiconductor B2 is conduct-connected with a detection part 3 of the subcutaneous contaminant substance. When the subcutaneous contaminant substance is alkaline,the metal 1 is selected. Electrodes conduct-connected with the detection part 3 and the other electrodes are conduct-connected with each other in a non skin contact area, and the detection part 3 and a counter electrode are spatially separated and skin-contacted. Inverse iontophoresis is elicited and the subcutaneous contaminant substance oozes onto the detection part 3 by a closed circuit current including a subcutaneous area to be reacted and detected.
