A chemiluminescent enzyme immunoassay method whereby a target substance such as a protein is assayed. This chemiluminescent enzyme immunoassay method comprises: the step of capturing an immune complex containing an enzyme-labeled antibody, which is labeled with an enzyme acting a chemiluminescent substrate, and the target substance on a support having no solution layer; the step of overlaying a support membrane containing the chemiluminescent substrate on the immune complex having been captured above; and the step of measuring the luminescence dose caused by the reaction between the enzyme-labeled antibody and the chemiluminescent substrate to thereby quantify the target substance. Since a highly sensitive chemiluminescent enzyme immunoassay is conducted by using a non-liquid phase type reaction system in the chemiluminescent enzyme immunoassay method as described above, multiple items can be assayed by using only a small amount of a specimen and, furthermore, the target substance can be assayed at a high sensitivity thereby without resorting to any troublesome procedures such as pipetting a reagent.
