Abstract

One of embodiments is a semiconductor micro-analysis chip for detecting particles in a sample liquid. The chip comprises a semiconductor substrate, a first flow channel provided on the semiconductor substrate to allow the sample liquid to flow therein, a second flow channel provided at a different position from the first flow channel of the semiconductor substrate to allow the sample liquid or an electrolyte solution to flow therein, a contact portion where a portion of the first flow channel and a portion of the second flow channel abut each other or intersect one another with a partition being arranged between the flow channels, and a fine hole provided on the partition of the contact portion to allow the particles to pass therethrough.
