An electronic device includes a first body and a second body. The first body includes a first main body and a first magnetic element fixed in the first main body. The second body includes a second main body, a supporting unit, a second magnetic element, and a third magnetic element. The second main body is adapted to hold the first body. The supporting unit is pivoted to the second main body. The second magnetic element is fixed in the second main body. The third magnetic element is slidably configured in the second main body to restrict a rotation of the supporting unit relative to the second main body. When the first body leans against the second main body, the third magnetic element is subject to a magnetic attraction force from the first magnetic element and escapes from the supporting unit, so that the supporting unit supports the first body.
