PROBLEM TO BE SOLVED: To provide an error estimation device and an error estimation method, estimating an estimation width of an analysis value in a numerical solution in consideration of a numerical value related error, an error causing an error of an input value such as a boundary condition, and an error causing geometric dimensional tolerance. SOLUTION: This error estimation device has: a geometric sensitivity calculation means (a procedure A) calculating sensitivity exerted by increase/decrease of a value of the error width and an error factor with a geometric dimension as the error factor on an attention value in the numerical solution of a prescribed phenomenon; an input value sensitivity calculation means (a procedure B) calculating sensitivity exerted by the increase/decrease of the error width and an error factor with the input value as the error factor on the attraction value in the numerical solution of the prescribed phenomenon; a numerical analysis error width acquisition means (a procedure C) acquiring the error width of a numerical analysis error of the prescribed phenomenon as an error factor; and an error estimation means estimating the error of the attraction value by use of at least one of the error factor of the error width acquired in the procedure C and the sensitivity and the error width calculated in the procedure B or the procedure A (S117).
