Claim:
1. A sensor, capable of at least one of detecting and quantifying a target substance contained in a biological sample, comprising: a cavity including: the second end being on an opposite side of the cavity from the first end; a suction opening disposed at the first end of the cavity, the suction opening communicating the cavity to outside of the sensor; a working electrode disposed inside of the cavity; a counter electrode disposed inside of the cavity; and a detecting electrode disposed inside of the cavity closer to the second end than to the first end, the detecting electrode disposed toward the suction opening from the back wall and spaced apart from the side wall of the cavity; wherein the side wall of the cavity includes a concave portion; the back wall has a planar shape; the side wall is disposed so that the diverter is configured to extend a path from the suction opening to the detecting electrode; a width of the cavity along the back wall is larger than a width of the cavity along the path from the suction opening to the detecting electrode; and the proportions of the sensor satisfy the relationship: in which D
