PROBLEM TO BE SOLVED: To provide a measurement chip higher in sensitivity than before, a measurement device on which the measurement chip is disposed, and a measurement method using the measurement chip.SOLUTION: A central position of a dielectric substance 11 is provided with a specific pattern 12 which is a place where a hole 13 is omitted (the hole 13 is not formed). The specific pattern 12 is a place in an arrangement mode different from a periodical arrangement. A periodic structure by the hole 13 functions as a mirror reflecting light of a specific wavelength region (for example, 620 nm to 680 nm). Here, the specific pattern 12 functions as a space surrounded with such a mirror. Thereby, the specific pattern 12 functions as a resonator for resonating light of the specific wavelength. Consequently, when the chip 1 is irradiated with light, light alone of the specific wavelength region can be emitted from the specific pattern 12 with an extremely high SN ratio.SELECTED DRAWING: Figure 3 |
