PURPOSE: To provide a conductor end face antenna which can be acted as an antenna, and which can be set on a metallic board 1 without protruding the antenna to an outside by providing the closed circuit of a high aspect rate on an end face 2 of a the metallic board 1.

CONSTITUTION: A closed circuit 4 of the high aspect rate which is long in the end face 2 direction, and which is short in the direction vertical to the end face 2 is formed of a metallic wire 3 along the end face 2 on the end face of the metallic board 1. Then, the neighborhood of the center of the metallic line 3 spread along the end face 2, and the end face 2 of the metallic board 1 corresponding to the neighborhood of the center of the metallic wire 3 are used as a power feeding point or power receiving point 5.
