METHOD OF PRODUCING FLOW PASSAGE DEVICE AND FLOW PASSAGE DEVICE

摘要

A flow passage device includes a first base body having a first hole and a second base body having a second hole connected to the first hole to form a flow passage. A first portion formed around the first hole has a specified shape for holding an adhesive. The second base body has a high-wettability surface around the second hole with a low-wettability surface disposed proximate the high-wettability surface, and at least part of the high-wettability surface has a shape matching at least part of the specified shape. The first and second base body are bonded to each other with the adhesive to form the flow passage by aligning the at least part of the first portion with the at least part of the high-wettability surface with positions of the first and the second holes aligned with each other.

主权项

1. A flow passage device that includes a first base body having a first hole and a second base body having a second hole connected to the first hole to form a flow passage,
wherein the first base body has a first portion around the first hole, the first portion having a specified shape for holding an adhesive, wherein the second base body has a high-wettability surface around the second hole with a low-wettability surface disposed proximate the high-wettability surface, and at least part of the high-wettability surface is patterned to have a shape that matches at least part of the specified shape of the first portion of the first base body, and wherein the first base body and the second base body are bonded to each other with the adhesive to form the flow passage by aligning the at least part of the first portion with the at least part of the high-wettability surface with a position of the first hole aligned with a position of the second hole.
