Abstract
An analysis device including a flow channel member, a suction mechanism, and a measurement unit. The flow channel member includes a flow channel; The suction mechanism is connected to a first end of the flow channel member and is configured to introduce a liquid sample from a second end of the flow channel member to the flow channel and hold the liquid sample between fluid layers in a part of the flow channel. The measurement unit includes a light irradiation unit a light reception unit configured to receive light from the part of the flow channel and the contents of the part of the flow channel when irradiated by the light irradiation unit. The measurement unit includes an aperture member to limit light from the light irradiation unit and includes an opening having an opening width shorter than the length of the part of the flow channel.
