A suspension board with circuit has a metal supporting board, an
insulating layer formed on the metal supporting board, a conductive
pattern formed on the insulating layer and including a terminal portion
for connecting to an external terminal, and an antistatic barrier layer
formed on the conductive pattern. The antistatic barrier layer includes a
metal thin film and a semiconductive layer having at least one end facing
the terminal portion and at least the other end in contact with the metal
supporting board.
