Provided are an analysis chip and a sample analysis device by which it is possible to perform analysis rapidly and accurately on a plurality of items simultaneously using a small amount of liquid for measurement. An analysis chip (10) is provided with: a substrate (20) formed in a substantially disc shape; an insertion hole (22) formed in the center of the substrate (20), a liquid to be measured being inserted into the insertion hole (22); and micro-flow paths (23) into which the liquid to be measured can be guided from the insertion hole (22) by capillary action, each of the micro-flow paths (23) having therein a plurality of types of antigens (30) that are fixed in place with gaps therebetween, the antigens (30) selectively reacting to components in the liquid to be measured.
