PROBLEM TO BE SOLVED: To provide a semiconductor device containing a resistor element that easily obtains a desired resistance value. SOLUTION: In the semiconductor device, a first well (3) having second conductivity which is opposite to first conductivity is formed in the first-conductivity surface layer of a semiconductor substrate. A pair of a current entrance and an exit (4 and 5) connected to the first well (3) makes current flow to the well (3) in the direction parallel to the surface of the substrate. Between the paired current entrance and the exit (4 and 5), a first-conductivity second well (9) is arranged which is made shallower than the first well (3). COPYRIGHT: (C)2006,JPO&NCIPI
