A slide electronic device includes a first body, a second body, and a slide mechanism. The slide mechanism includes a first connecting member and a second connecting member. One end of the first connecting member is pivotally connected to the first body, an opposite end is pivotally connected to the second body, one end of the second connecting member is pivotally connected to the first body, and an opposite end is pivotally connected to the second body. A distance between rotary axes of the two ends of the first connecting member exceeds that of the second connecting member. When the second body slides relative to the first body, the first connecting member and the second connecting member are rotated relative to the first body and the second body until an end of the second body resists the first body and the second body is angled.
