There is provided a chip-type sampling apparatus to be attached so that a sampling side of the sampling apparatus faces the skin, the apparatus including a porous adsorption layer that faces the sampling side and has a pore diameter in a range of 0.1 to 1000 nm. One example of the adsorption layer includes at least three porous layers with different central pore diameters that are laminated from the sampling side in descending order of the central pore diameters. The sampling apparatus should preferably also include a layer that sucks air through the adsorption layer.
