The purpose of the present invention is to provide a semiconductor device capable of reducing a skew by preventing a variation in delay times of signals. The semiconductor device comprises: a first signal line (508) formed in a first wiring layer formed on a semiconductor substrate, and disposed in a first direction; first and second shield lines (509, 510) formed in the first wiring layer, disposed on both sides of the first signal line in the first direction, and given a first fixed potential; and a plurality of third shield lines (701) formed in a second wiring layer formed on the semiconductor substrate, disposed with a first wiring width and at a first wiring interval in a second direction almost orthogonal to the first direction, to partially overlap with each of the first signal line and the first and second shield lines, and given the first fixed potential.
