MICRO-FLOW PATH DEVICE AND MICRO-FLOW PATH ANALYSIS DEVICE

摘要

Provided is a micro-flow path device in which a micro-flow path is formed by a flexible tape having a plurality of layers, which, while being capable of being wound into a roll, configures a micro-flow path with high shape retention when being used in analysis. A micro-flow path device wherein a micro-flow path (m) is formed by a flexible tape (2) having a plurality of layers comprises: a lateral wall forming layer (20) which forms a lateral wall of a micro-flow path; and a lid layer (20 (21)) which covers an aperture in the layering direction of the micro-flow path. The lateral wall forming layer has a higher bend elastic constant than the lid layer. With the lid layer bend elastic constant being low, a micro-flow path with high shape retention when used in analysis is configured in which implementing ease of bending of the tape overall and winding same in a roll with a desired winding diameter is possible, while, when the tape is unwound and used in analysis, the bending stress when wound is released and the stress is lowered, recovering elastically to a smaller distortion than the lateral wall forming layer with the comparatively high bend elastic constant.
