According to the embodiments, a semiconductor package includes a semiconductor chip, a first conductive layer, a second conductive layer, and a power feeder. The semiconductor chip is provided on a substrate, is sealed with a resin, and contains a transmission/reception circuit. The first conductive layer is grounded and covers a first region on a surface of the resin. The second conductive layer is not grounded and covers a second region on the surface of the resin other than the first region. A power feeder electrically connects the semiconductor chip to the second conductive layer.

According to one embodiment, a wireless device includes a circuit board, a semiconductor chip, a sealing resin, a conductive film, and an antenna element. The semiconductor chip includes a transmitting/receiving circuit and is mounted on the circuit board. The sealing resin seals the semiconductor chip. The conductive film covers a first surface portion of the sealing resin. An aperture is formed in a portion of the conductive film that corresponds to a second surface portion of the sealing resin other than the first surface portion, and the second surface portion is included in a side surface of the sealing resin and closest to an antenna terminal connected to the antenna element.
