A wireless network card contains a card-shaped board on which an electronic circuit unit is arranged; radiating conductor patterns and feeding lines that are provided on one surface of the board; a ground conductor patterns, serving as a ground of the radiating conductor patterns, provided on the other surface of the board. Also, choking slits set to have a length that makes it difficult for a high-frequency current to flow through the electronic circuit unit are formed in a region of the ground conductor pattern that does not overlap the feeding lines, between the electronic circuit unit and the radiating conductor patterns.
