A wired circuit board is provided that is formed by connecting a first
wired circuit board and a second wired circuit board, which include a
first connection terminal and a second connection terminal, respectively.
A solder bump is provided to continuously extend over surfaces of the
first connection terminal and the second connection terminal to
mechanically couple the first wired circuit board and the second wired
circuit board. Consequently, the solder bump is not interposed between
opposed surfaces of the first connection terminal and the second
connection terminal, thereby allowing the electrical connection provided
by the solder bump to be confirmed by visual observation.
