Thin type fan and manufacturing method thereof

The invention discloses a thin type fan and a manufacturing method of the thin type fan. The manufacturing method of the thin type fan comprises providing plastics with a plurality of metallics, processing and forming the plastics into a shell body, removing the surface of partial shell body and forming a circuit wiring area on the shell body, and arranging a metal layer on the circuit wiring area. According to the thin type fan and the manufacturing method of the thin type fan, the arranging volume and the space of a control circuit board are removed so as to shorten the integrate height of the thin type fan, the height space can be used more effectively, and the variability of the circuit wiring of the fan can be increased so as to be beneficial for the thinning design of the fan.
