Abstract
A cell phone frame, and a method for manufacturing the same, includes a composite plate. The composite plate encloses an accommodation space for accommodating the cell phone. The composite plate includes a first plate and a second plate, a first side surface of the first plate having striations. The first side surface of the second plate and the first side surface of the first plate are rolled to connect, and the striations of which adjacent ones have a pitch of 0.005 mm to 0.03 mm account for more than 90% of all the striations.
