ABSTRACT:
A tip of a probe is sharpened and a level difference portion 6 in a boundary zone between a base portion 5 and an elastic functioning portion 4 is formed into a tapered configuration. The diameter of the elastic functioning portion 4 is made smaller than that of the base portion 5. Also, a part of the elastic functioning portion 4 is shaped into a constricted configuration. Also, the probe material is an optical fiber and this probe is composed of a core portion 2 that propagates light therethrough and clad portions 3 that differ in refractive index from each other. And the portion of the probe that excludes a aperture is clothed by a metal film cladding 7.
