<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a micro fluid circuit without a need of alignment of a mask, or misregistration of the mask at low manufacturing costs. <P>SOLUTION: In this micro fluid circuit manufacturing method, a transparent upper plastic substrate 32 is laminated on a light-absorbing lower plastic substrate 33, and the upper plastic substrate and the lower plastic substrate are fused and jointed by radiating lights through the upper plastic substrate. A micro channel 31 is provided on a bottom face of the upper plastic substrate and/or a top face of the lower plastic substrate. This method includes a step for forming a light-attenuating area 34 on the plastic substrate, where, when lights are radiated through the upper plastic substrate, a light-transmitting volume to the micro channel is attenuated. <P>COPYRIGHT: (C)2008,JPO&INPIT |
