Abstract
An observation chipincludes: a plurality of substratesstacked in a thickness direction Z of the substrates; a first channelextending along a first axis Oalong the substrates; a surrounding channelsurrounding the first channel all around in a cross section orthogonal to the first axis in the first channel from an end of the first channel to an overall merging point Pof the first channel, integrated with the first channel, and forming a second channelthat extends along a second axis Oalong the substrates; and an observation sectionprovided on a side farther away from the first channel than the overall merging point in the second channel, and transmitting electromagnetic waves from outside to the second channel. A length of the second channel in the thickness direction is constant from the overall merging point to the observation section.
