1. A sample analysis method, comprising:

  • (a) applying a voltage between a first electrode pair, which is formed so as to sandwich a migration pathway of a sample such that an electric field is formed in a direction intersecting a migration direction of the sample;

    (b) causing a first current, which arises from a redox reaction, to flow to the first electrode pair by placing, within the migration pathway interposed between the first electrode pair, a solution including an electrochemically active molecule that produces the redox reaction at the first electrode pair;

    (c) causing the sample to migrate along the migration pathway interposed between the first electrode pair; and

    (d) measuring an amount of change in the first current produced by migration of the sample.
