Abstract
Abstract A cantilever for an atomic force microscope, has a probe formed by a structure at least partially including a linear needle crystal. A method of manufacturing the cantilever comprises the steps of applying adhesive to a distal end portion of a cantilever body and placing on the adhesive, in a state where the cantilever body is held substantially horizontally, a structure having the shape of at least four needle crystals combined with one another so as to bond the structure to the distal end portion of the cantilever body.
