A semiconductor device includes a first insulating layer, which is formed
on a semiconductor substrate (not shown), and formed with a concave
portion, and an electric fuse which has a conductive member, a first
terminal provided on one end and a second terminal provided on the other
end of the conductive member, and which is provided on the first
insulating layer. The first insulating layer is embedded with the
conductive member. The conductive member has a flowing-out region in
which a material forming the conductive member flows out to the outside
of the concave portion, and is cut at a location different from the
flowing-out region.
