Abstract
A thin film resistor includes a high-resistance region and low-resistance regions which are formed at both ends of the high-resistance region. The high-resistance region includes first high-resistance regions and a second high-resistance region, and the first high-resistance regions are arranged at both side surfaces in a first direction in the second high-resistance region. The second high-resistance region has a higher sheet resistance than that of the first high-resistance regions.
