A wearable device includes: a metal middle cover, a metal bottom cover, a printed circuit board PCB, and a gap. The metal middle cover encircles the wearable device for a whole circle and serves as an exterior of the wearable device. The metal bottom cover is located under the metal middle cover and serves as a rear cover of the wearable device. The gap with a preset width exists between the metal middle cover and the metal bottom cover, and serves as a slot antenna of the wearable device. The PCB is in an inner side of the metal middle cover, and is located above the metal bottom cover. The PCB is electrically connected to the metal middle cover by using a feed point, and feeds power to the metal middle cover.
