It is a problem to provide a microchip for analysis which is miniaturized, is disposable for ease to use, and does not have a risk of contamination in flow channels. On a substrate 2, a first flow channel having a buffer solution supply channel 6 and a reaction bath section 3, a second flow channel having a sample solution supply channel 5 and a waste solution channel 7, and a connecting channel 9 connecting both the flow channels upstream of the reaction bath section 3 are provided. The waste solution channel 7 and the reaction bath section 3 are connected to a waste solution tank 8 and a pump 11. After a ligand is modified in the reaction bath section 3, a sample solution is allowed to flow in the sample solution supply channel 5 and the waste solution channel 7, and a buffer solution is allowed to flow in the buffer solution supply channel 6, the connecting channel 9 and the waste solution channel 7, subsequently to flow in the buffer solution supply channel 6 and the reaction bath section 3. Then, a temperature adjusting section 13 and the pump 11 are set such that a desired temperature of a fluid and a flow rate are obtained. Subsequently, the sample solution is supplied to the sample solution supply channel 5, the connecting channel 9, and the reaction bath section 3, a binding reaction is brought between the ligand and an analyte in the sample solution, and the state of binding is detected.

The present invention has an object to obtain an optical waveguide probe which is formed in a hook form to illuminate and detect light by a manufacture using a silicon process. This optical waveguide probe is formed in a hook form and structured by an optical waveguide 1 sharpened at a probe needle portion 5 and formed of dielectric and a substrate 2 supporting this optical waveguide 1. This optical waveguide 1 is formed overlying the substrate 2. The optical waveguide 1 is structured by a core 8 to transmit light and a cladding 9 smaller in refractive index than the core 8.
