A tape for detecting leakage of a sample is provided to reduce manufacturing cost and rising of credibility by broadening a reaction region and preventing leakage of residue of a reagent component, and to perform a leakage test efficiently. A tape for detecting leakage of a sample includes a support layer(110) and an adhesion reactive blending layer(120). The support layer is a transparent material. The support layer has a mold frame shape covering a dimensional shape of a target object. The adhesion reactive blending layer is laminated on a bottom region of the support layer. The adhesion reactive blending layer contains a reagent component and an adhesive component.
