Zusammenfassung:An inverted-F antenna includes a ground member, a first antenna member including a short-circuit portion rising perpendicularly from the ground member while being electrically coupled with the ground member, a flat plate portion extending from a top end of the short-circuit portion while being electrically coupled with the short-circuit portion, and a protrusion portion protruding from a part of an end of the flat plate portion; and a second antenna member including a conductor pattern that includes a power supply portion at one end portion thereof, has a width increasing toward an opposite end, and is electrically coupled with the flat plate portion. The second antenna member is located between the ground member and the flat plate portion with a predetermined distance from an end of the flat plate portion opposite to the protrusion portion.
