PROBLEM TO BE SOLVED: To provide an electrically resistive material with high electric resistance and little dependence of electrical resistivity on temperature, which hardly generates noise caused by a magnetic field formed when current passes. SOLUTION: The electrically resistive material includes 0.1% or less C, 5% or less Si, 6% or less Mn, 9-32% Cr, 6-25% Ni, 0.2% or less N, 0-3% Mo, 0-4% Cu, 0-5% Al, 0-0.4% Ti, 0-0.4% Nb, and 0-0.005% B, and has controlled values A and B respectively of 78 or more and 14 or more, which are respectively defined in the expressions (1) and (2): A=0.008×(%Cr)<3> -0.43×(%Cr)<2> +8.03×(% Cr)+6.8×-(%Si)+10.9×(%Al)+0.56×(%Mo)+0.92×(%Ni)... (1), and B=(% Ni)+(%Cu)+0.6×-(%Mn)+9.69×(%C+%N)+0.18×(%Cr)-0.11×(%Si)<2> ... (2).
