<p>There is provided a microfluidic device capable of preventing the flow of a fluid from being interrupted by bubbles generated in a micro flow passage. A microfluidic device (10) wherein a micro flow passage (16) having a substantially constant height is formed for allowing a fluid to flow therein and wherein a narrow portion is formed in a portion of the micro flow passage by forming a columnar portion (12c) or the like in the micro flow passage, an extending recessed portion (14c) for extending the micro flow passage upwards is formed upstream of the narrow portion, and a plurality of raised portions extending in substantially parallel to longitudinal directions of the micro flow passage are formed on a portion of the bottom face of the micro flow passage facing the extending recessed portion if necessary.
The features above being suitable for trapping a bubble in said flow passage.</p> |
