Abstract: There is provided an apparatus including a chip containing metal bodies capable of exciting localized surface plasmon resonance at a first surface, and an analyzer unit that performs a scan of the first surface of the chip, in a state where the first surface is in contact with a sample, with a laser in at least a one-dimensional direction and records scattered light, which has been enhanced at the first surface, in association with the scan. The chip includes a substrate, a first layer where concave and convex structures are repeatedly provided on the first surface of the substrate; and a second layer that contains the metal bodies and is provided via the first layer.
