We propose a micro liquid prism. Two flat transparent plates float on a liquid droplet and these plates serve as prism faces. The two plates are positioned　automatically by surface tension, just by putting the plates on the ellipsoidal droplet. Therefore the proposed prism can be fabricated accurately in micro scale without difficulty. As the liquid and the plates are encapsulated by Parylene, the prism can retain its shape. The prism which faces were 400μm in diameter and whole size was smaller than 1mm³ was fabricated. The adequate function of the fabricated prism for Surface Plasmon Resonance (SPR) measurement was verified.
