PROBLEM TO BE SOLVED: To provide a band gap calculation device and a band gap calculation program that can calculate a band gap with more accuracy.SOLUTION: The band gap calculation device is configured to: in a range of an input h&ngr; value (a range between points P1 and P2), plurally set a calculation range of a predetermined width in a different range by shifting the calculation range thereof at predetermined intervals; while changing a value of the predetermined width, out of each calculation range, identify the calculation range in which a Tauc curve is the closest to a linear line; calculate a liner line L1 extending along the Tauc curve in the identified range; and calculate the h&ngr; value at an intersection point P3 of the linear line L1 and a predetermined reference line (a lateral axis or a baseline linear line L2) or P6 thereof as a band gap. |
