A wired circuit board includes a wiring formation portion, a terminal
formation portion, and a middle portion formed therebetween. The wiring
formation portion includes a first conductive layer formed on a first
insulating layer, and a second conductive layer formed on a second
insulating layer so as to overlap the first conductive layer in a
thickness direction. The terminal formation portion includes the first
and second conductive layers formed in parallel in the same plane. The
middle portion includes the first conductive layer formed on the first
insulating layer, and the second conductive layer formed on a portion of
the second insulating layer extending from the wiring formation portion
to a mid-point between the wiring formation portion and the terminal
formation portion, and formed on a portion of the first insulating layer
extending from the mid-point to the terminal formation portion.
