An exemplary flexible printed circuit board ( 2 ) includes a wiring layer ( 21 ). The wiring layer includes a number of conductive lines ( 211 ). Each of the conductive lines includes a finger ( 213 ), a line portion ( 212 ) and a junction portion ( 214 ) between the finger and the line portion. A width of the finger is greater than a width of the line portion, a width of the junction portion gradually changes from the width of the line portion to the width of the finger. The flexible printed circuit board has high reliability.
