1. A measurement tool comprising:
a measurement tool body including a sample collection unit for collecting a liquid sample by a capillary phenomenon, and a liquid feed channel; and
a lid body attachable to and detachable from the measurement tool body,
wherein:
the lid body includes a tubular insertion portion;
the tubular insertion portion is configured to fit into a recess defined in the measurement tool body;
the liquid feed channel includes an upstream side channel and a downstream side channel;
a space is defined, into which an upstream side end of the sample collection unit and a downstream side end of the upstream side channel open, in a first state in which the lid body is attached to the measurement tool body;
the downstream side channel is connected to a downstream side end of the sample collection unit; and
the space is open in a second state in which the lid body is separated from the measurement tool body, and the space is closed and the upstream side channel and the sample collection unit are connected in the first state in which the lid body is attached to the measurement tool body.
