Provide is a sample analysis tool whose reactivity and reproducibility in analysis can be prevented from decreasing. The sample analysis toolof the present invention includes a development memberand a plastic base, and at least part of the development memberis in contact with the plastic base. The sample analysis toolfurther includes a hydrophilic component layer, and the hydrophilic component layeris formed on part or the whole of at least one of a surface of the plastic baseand a surface of the development member. It is particularly preferable that the hydrophilic component layercontains sucrose or N-methyl glucosamine. In the sample analysis toolof the present invention, since the hydrophilic component layeris formed on part or the whole of at least one of the surface of the plastic baseand the surface of the development member, it is possible to prevent the adhesion of a hydrophobic component(s) derived from the plastic base
