Abstract: The wireless communication device has a first radiation element, which includes a first line path being extended between a first end and a second end and performs communication at a first frequency. The device also has a second radiating element coupled to the first radiating element and resonating at a second frequency, which element has a second line path extending from a first connecting portion connected to the sheet metal to a third end portion near the first end portion, and a third path line extending from an intermediate point between the first connecting portion and the third end portion to the fourth end portion. And a power supply circuit for a third frequency is connected to the fourth end via a cutoff circuit which cuts off the second frequency. With this configuration, the wireless communication device enables the communication in more frequency bands.
