<P>PROBLEM TO BE SOLVED: To provide a flow passage body that prevents fragments of a cover from remaining in a flow passage when the cover is separated from a base body. <P>SOLUTION: The flow passage body includes: a base body 1 having a flow passage 1a formed therein; a cover 2 provided between the flow passage 1a and an outer surface of the base body 1, formed integrally with the base body 1 so as to seal the flow passage 1a, and separable from the base body 1 by applying a mechanical load; and a projecting member 3 connected to the outer surface of the cover 2 via a bonding member 4 which is smaller in plan view than the cover 2. In separating the cover 2 from the base body 1 by applying a mechanical load to the cover 2 via the projecting member 3, the cover is bonded to the projecting member 3, thereby preventing the cover 2 from being divided and entering inside the flow passage 1a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
