Even though electron holography was invented to correct spherical aberration of electron lenses, it can also be used for observing electromagnetic micro-fields. [1] Since electromagnetic properties of materials or devices are strongly related to their electromagnetic micro-fields, observation of such micro-fields is an important experiment for materials science or device engineering. In this paper, we present an application of conventional electron holography, two-dimensional visualization of
