A moistureproof unit for a moistureproof container for accommodating a biochemical test strip is manufactured by uniformly distributing a moistureproof layer of a hydrophilic polymer material on a surface of a carrier, and including water absorption semicircular units in the hydrophilic polymer material. The moistureproof unit is disposed in a container body which houses the biochemical test strip. The moistureproof unit absorbs the moisture in the container body via the moistureproof layer.
