Abstract
An antenna device (100) includes an antenna element (101) and an electric conductor plate (102) provided so as to face the antenna element (101). The antenna element (101) and the electric conductor plate (102) are short-circuited by a short-circuit section (104). The antenna element (101) is connected with both of external and internal electric conductors (122) and (123) constituting a feed line (121).
