Abstract
A microchip includes a clad layer having a channel through which a sample flows, and an optical waveguide formed within the clad layer and having a higher refractive index than the clad layer. The optical waveguide is formed to act on the channel optically. Thus, the sample flowing in the channel can be analyzed with high accuracy even in the microchip having a fine structure.
