Abstract: Provided is a chip that does not require high-accuracy discharge amount control for a liquid delivery pump and can suppress the entrainment of air bubbles. A chip 1 for test or analysis is provided with a flow path 4 through which a fluid is delivered, the chip 1 including: a first flow path 5 through which a first fluid is delivered; a second flow path 6 through which a second fluid is delivered; a merging portion 8 configured to be provided on a downstream end portion 5a side of the first flow path 5 and merge the first fluid and the second fluid; a first connection flow path 9 configured to connect the first flow path 5 and the second flow path 6 at the merging portion 8 and have a liquid delivery resistance higher than a liquid delivery resistance of the first flow path 5; a degassing flow path 13 configured to be connected to the second flow path 6 on a downstream side of the first connection flow path 9; a third flow path 7 configured to be provided on a downstream side of the merging portion 8; and a second connection flow path 10 configured to connect the first flow path 5 and the third flow path 7 and have a liquid delivery resistance higher than the liquid delivery resistance of the first flow path 5.

Abstract: To provide a measurement tool and a liquid feeding method in the measurement tool in which loss of a quantitatively collected liquid sample is unlikely to occur and measurement accuracy may be improved. A measurement tool (1) is provided with a measurement tool body (2) and a lid body (3) attachable to and detachable from the measurement tool body (2), in which a liquid feeding channel includes an upstream side channel (11) and a downstream side channel (12), a space into which a sample collection unit (13), an upstream side end, and a downstream side end of the upstream side channel (11) open is formed of the measurement tool body (2) and the lid body (3), the downstream side channel (12) is connected to a downstream side end of the sample collection unit (13), the space is put into an opened state in a state in which the lid body (3) is separated from the measurement tool body (2), and the space is closed and the upstream side channel (11) and the sample collection unit (13) are connected when the lid body (3) is attached to the measurement tool body (2).
