A holder including a fixed base, a rotational base, a first arm and a second arm is provided. The rotational base is rotatably disposed on the fixed base and has a supporting plane and two openings. The first arm and the second arm are disposed in the rotational base, and pass through the two openings, respectively, wherein the first arm is coupled with the fixed base. When a hand-held electronic device is located between the first arm and the second arm and is rotated along with the rotational base relative to the fixed base, the fixed base drives the first arm to move relative to the rotational base so as to hold the hand-held electronic device by the first arm and the second arm.
