Abstract
Provided is an inspection chip with simplified channel switching structure, which is generally complicated. An inspection chipincluding a chip main bodyhaving a specimen introduction channel, an adsorption channel including an adsorption unit, a first waste liquid channel, a recovery liquid introduction channel, and a detection channel including a detection unit; and a rotary valveattached to the chip main bodyso as to be rotatable about a rotation axis, the rotary valvehaving a plurality of connection channels, the plurality of connection channels being arranged so that the rotary valveis capable of taking at least a first state and a second state when the rotary valverotates about the rotation axis, the first state being a state in which the specimen introduction channel, the adsorption channel, and the first waste liquid channel are connected so as to be provided in this order from an upstream side, and the second state being a state in which the recovery liquid introduction channel, the adsorption channel, and the detection channel are connected so as to be provided in this order from the upstream side.
