    摘要: Provided is an easy to determine immunochromatography detection device 100 that detects a target substance 1 that may be contained in a sample fluid 10. The detection device comprises: a flow path 101 for the sample fluid; and detection parts 106, 108 to which capture substances 6, 8 are fixed. In one embodiment, an MIM structure is formed when the target substance is included in the sample fluid at the detection parts, and a color is produced at the detection parts by resonance absorption. The MIM structure comprises a metal thin film 7 (M layer) that is formed on a support 9, either a capture substance/target substance/reference substance composite layer or a capture substance/reference substance composite layer (I layer), and metal fine particles 4 (M layer) with which a reference substance 2 is labeled.
