An interconnect structure includes: an interlayer insulating film formed on a lower metal layer; a contact hole formed in the interlayer insulating film to expose the lower metal layer; a plurality of carbon nanotubes formed on a bottom of the contact hole; an wiring metal filled in the contact hole to fill gap between the plurality of carbon nanotubes; and an upper wiring formed above the contact hole. A Ti layer is formed between the plurality of carbon nanotubes and the upper wiring.
