A wire fixing frame for fixing at least one wire on a substrate is described. The wire fixing frame includes a main part, a first fixing part, a second fixing part, and an extending part. A wire outlet is defined between the extending part and the first fixed part, and a wire inlet is opposite to the wire outlet. A wire hold space is defined among the main part, the first fixing part, the second fixing part, and the substrate. The wire passes from the wire inlet to the wire outlet through the wire hold space, and the wire is fixed at a position by a round corner of the first fixing part and the extending part.
