The essential principles of information transmission using handwritten characters are "identity" and "distinction" between the spatial handwritten characters, therefore their stroke structure must be defined by the spatial handwritten characters themselves. In this paper, structure of handwritten characters is analyzed using an opposing relation between two continuous curves on two dimensional space. Firstly, a fundamental character element (FCE) is defined as simple two-dimensional curves, such as a straight line and an arc. Secondly, a character to be considered is confined to a connection of two FCEs and an opposing relation of two characters is defined. Thirdly, using the opposing relation of two characters, structure of each character is analyzed. As to the system of Arabic numerics, there are some pairs of characters whose opposing relations are distinctive. A distictive opposing relation of two characters can be characterized only by some quantities such as the angle of two FCEs and degree of curvature of a FCE, and the structure of the characters can be defined by their distinctive opposing relation. Finally the the structure of Arabic numerics are discussed.
