Two concentric electrodes composed of a circular disc and an outer circular flat ring placed on one plane are used recently to detect moisture content of woods or other materials by measuring dielectric constant or power factor. In spite of the convenience of the measurement by only pressing them on the half surface of dielectrics, the error may be caused especially for thin dielectrics due to non uniform distribution of the field. It is worth mentioning from the stand point of the application to moisture content meter to clear the electrostatic field as well as to determine the capacity of electrodes. The analysis of potential and field has been given by Ataka's method which is able to solve axially symmetric problem. The potential function obtained has been discussed on its error and compared with experiments by field mapping. Furthermore, the characteristics of concentric planar electrodes has been compared with those of coplanar strip electrodes.
