<p><P>PROBLEM TO BE SOLVED: To provide an inspection microchip constituted so as to prevent the closure of a flow channel inlet caused by the accumulation of air bubbles in the flow channel inlet reaching a small diameter liquid sending control passage from a large-diameter flow channel on an upstream side, to temporarily stop the passage of a liquid to permit the passage of the liquid under predetermined pressure at a proper period while preventing the passage of air bubbles to a deownstream side in a liquid sending control part provided on the flow channel of the inspection microchip, enhanced in the precision of the liquid sending control part, capable of performing accurate inspection and excellent in reliability, and an inspection device using it. <P>SOLUTION: The flow channel is equipped with the liquid sending control part constituted so as to cut off the passage of the liquid until the liquid sending pressure in the positive direction from the upstream side to the downstream side reaches predetermined pressure while passing the liquid by the application of liquid sending pressure higher than the predetermined pressure and the liquid sending control part is equipped with an air bubble capturing means for capturing air bubbles so as to prevent the air bubbles in the liquid flowing through the flow channel from flowing to the downstream side to pass only the liquid. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
