PROBLEM TO BE SOLVED: To precisely approximate a function even in a large number of input variables, and to reduce a learning cost required for the approximation. SOLUTION: This function approximation device (C) is provided with: an input variable input means (C7A) of which the input layer (Na) comprises respective input elements (s<SB>X1</SB>, s<SB>X2</SB>to s<SB>Xn</SB>, s<SB>v1</SB>, s<SB>v2</SB>to s<SB>vn</SB>, s<SB>θ1</SB>, s<SB>θ2</SB>to s<SB>θn</SB>, s<SB>ω1</SB>, s<SB>ω2</SB>, to s<SB>ωn</SB>) input with respective values of the three or more of input variables (x, v,θ,ω) and for inputting respectively the respective values of the three or more of input variables (x, v,θ,ω), and; an intermediate variable computing means (C7C) set with input variable sets with the two input variables out of the three or more of input variables (x, v,θ,ω) serving as one set, and for computing respectively respective values of intermediate variables y, based on each value of the one input variable in each input variable set, and each first output sensitivity computed based on each value of the other input variable in each input variable set.
