A testing device comprising:
- a porous flow path member in which a flow path for flowing a sample is formed;
- and
- a resin layer provided at at least one position over the flow path member,
- wherein the resin layer comprises a porous body formed of a hydrophobic material, and
- wherein a reagent reactive with the sample is formed as a solid phase over a surface of the resin layer facing the flow path member and inside voids of the resin layer,
- wherein the resin layer comprises a first resin layer and a second resin layer that are provided over the flow path member,
- wherein
- the first resin layer comprises the porous body comprising the hydrophobic material,
- the first resin layer comprises at least a capture antibody as the reagent reactive with the sample over a surface of the first resin layer facing the flow path member and inside voids of the first resin layer, and
- the second resin layer comprises a labeled antibody over a surface of the second resin layer facing the flow path member.
