An analysis apparatus comprises a flow cell which has a flow passage for a liquid containing a tangible component; an image pickupper which picks up images of the liquid flowing through the flow passage; an adjuster which adjusts a relative position of the flow cell with respect to the image pickupper in relation to an optical axis direction of the image pickupper and a direction in which the liquid flows through the flow passage; and a controller which determines an image pickup position of the flow cell in at least one of the optical axis direction and the direction in which the liquid flows, on the basis of a number of pieces of the tangible component in focusing states existing in the images of the liquid picked up by the image pickupper at a plurality of positions at which the relative position differs.
