Abstract: The present invention is object to provide a protein chip holding tool that is capable of effectively executing analysis work by preventing protein from being denatured and/or inactivated due to drying while attempting to make the amount of spotting of protein test samples to be spotted on a substrate very slight, and said a chip holding tool comprising a substrate holding member 39 in which at least one or more substrate holding portions 41 holding the substrate 35, a resilient holding member 45 that covers the upper surface of the substrate holding member 39, a resilient body engaging portion 51 holding the resilient body 37, and an opening and closing member 53 that is movably supported on the upper surface of the resilient holding member 45 and opens and closes the openings 45a.
