A wireless communication apparatus that includes a first antenna section having a first power feed point; a second antenna section having a second power feed point; a first electrically conductive plate extending between the first antenna section and the second antenna section; a second electrically conductive plate disposed substantially in parallel with the first electrically conductive plate and extending between the first antenna section and the second antenna section; and a short-circuiting member that electrically short-circuits the first electrically conductive plate and the second electrically conductive plate to each other such that a slit is formed by a part of a periphery of the first electrically conductive plate and a part of a periphery of the second electrically conductive plate.
