Abstract
An object is to provide a channel-forming substrate capable of suppressing protrusion of a bonding adhesive while maintaining rigidity. The channel-forming substrate includes a first substrate in which a hollow portion to be a liquid channel is formed and a second substrate bonded to the first substrate with a bonding adhesive, in the first substrate, a plurality of first grooves are intermittently formed in a bonding surface bonded to the second substrate, in the second substrate, a plurality of second grooves are intermittently formed in a bonding surface bonded to the first substrate, and in a case where the channel-forming substrate is viewed from above, the first grooves and the second grooves are arranged alternately so as to surround the hollow portion.

A channel-forming substrate comprising:
- a first substrate in which a hollow portion to be a liquid channel is formed;
- and
- a second substrate bonded to the first substrate with a bonding adhesive,
- wherein, in the first substrate, a plurality of first grooves are intermittently formed in a bonding surface bonded to the second substrate,
- wherein, in the second substrate, a plurality of second grooves are intermittently formed in a bonding surface bonded to the first substrate, and
- wherein, in a case where the channel-forming substrate is viewed from above, the plurality of first grooves and the plurality of second grooves are arranged alternately so as to surround the hollow portion, and
- wherein one or more of the plurality of second grooves are communicated with one of the plurality of first grooves.
A channel-forming substrate comprising:
- a first substrate in which a hollow portion to be a liquid channel is formed;
- and
- a second substrate bonded to the first substrate with a bonding adhesive,
- wherein, in the first substrate, a plurality of first grooves are intermittently formed in a bonding surface bonded to the second substrate,
- wherein, in the second substrate, a plurality of second grooves are intermittently formed in a bonding surface bonded to the first substrate,
- wherein, in a case where the channel-forming substrate is viewed from above, the plurality of first grooves and the plurality of second grooves are arranged alternately so as to surround the hollow portion, and
- wherein one of the plurality of first grooves and one of the plurality of second grooves, which are adjacent to each other, are arranged while not being communicated with each other via a bonding region, which has a length of 60 μm or less.
A method of manufacturing a channel-forming substrate, the method comprising:
- preparing a first substrate and a second substrate;
- forming, in the first substrate, a liquid channel through which liquid flows and intermittently a plurality of first grooves surrounding a circumference of the liquid channel;
- intermittently forming a plurality of second grooves in the second substrate;
- bonding the first substrate and the second substrate using a bonding adhesive so that the plurality of first grooves and the plurality of second grooves are arranged alternately in a case where the first substrate and the second substrate are viewed from above while being bonded to each other;
- and
- cutting the first substrate and the second substrate bonded to each other to divide the channel-forming substrate into a plurality of individual pieces.
