Abstract
A channel device includes a first substrate having a groove portion for forming a channel, and a second substrate having a protruding portion that covers the groove portion, the first substrate and the second substrate being bonded together with an adhesive. The protruding portion of the second substrate extends along the extending direction of the groove portion of the first substrate, and mutually corresponding parts of the protruding portion of the second substrate and the groove portion of the first substrate are in direct and linear contact with each other without an adhesive therebetween, and the channel is thereby formed.

A channel device comprising:
- a first substrate having a groove portion for forming a channel;
- and
- a second substrate having a protruding portion that covers the groove portion, the first substrate and the second substrate being bonded together with an adhesive,
- wherein the protruding portion of the second substrate extends along a direction corresponding to an extending direction of the groove portion of the first substrate, and
- wherein mutually corresponding parts of the protruding portion of the second substrate and the groove portion of the first substrate are in direct and linear contact with each other without an adhesive therebetween, and the channel is thereby formed.
A method for manufacturing a channel device including a first substrate having a groove portion for forming a channel and a second substrate having a protruding portion extending along a direction corresponding to an extending direction of the groove portion, the first substrate and the second substrate being bonded together with an adhesive, the method comprising the steps of:
- applying adhesive to a predetermined part of at least one of the first substrate and the second substrate;
- bonding the first substrate and the second substrate such that the groove portion of the first substrate and the protruding portion of the second substrate are aligned with each other;
- and
- applying pressure to at least one of the first substrate and the second substrate after the bonding so that mutually corresponding parts of the protruding portion of the second substrate and the groove portion of the first substrate are brought into direct and linear contact with each other without adhesive therebetween.
