An analysis device 1 is provided with: a flow channel 12c; a suction mechanism connected to one end of the flow channel, the suction mechanism being configured to introduce a trace amount of a liquid sample L from the other end of the flow channel 12c into an inside of the flow channel 12c and hold the liquid sample L in a part of the flow channel 12c; and a measurement unit 40 configured such that a light irradiation unit 41 for irradiating the liquid sample L held by the part of the flow channel member 12 with light and a light reception unit for receiving the light from the liquid sample L are disposed around the liquid sample L. The measurement unit 40 is provided with an aperture member 46 to limit the light directed from the light irradiation unit 41 toward the liquid sample L, the aperture member 46 including an opening having an opening width L2 shorter than a liquid length L1 of the liquid sample L held by the flow channel 12c in the flow channel 12c.
