Summary:PROBLEM TO BE SOLVED: To provide: a lead-free thick film resistor having a good electric property with small current noise while having a high resistance value; and a lead-free resistance paste which acts as a material thereof.SOLUTION: A resistance paste substantially comprises: thermally conductive particles made of a ruthenium dioxide; a lead-free glass frit; an organic vehicle; and an additive agent. The resistance paste includes, as the additive agent, 0.1-1.8 mass% of an organic tin compound in terms of a tin oxide. The organic tin compound is suitably a tin (II) octylate.SELECTED DRAWING: None 【課題】 高い抵抗値を有しながら電流ノイズの小さい良好な電気的特性を有する鉛フリーの厚膜抵抗体及びその材料となる鉛フリーの抵抗ペーストを提供する。【解決手段】 二酸化ルテニウムからなる導電性粒子と、鉛を含まないガラスフリットと、有機ビヒクルと、添加剤とで実質的に構成される抵抗ペーストであって、該添加剤として酸化スズ換算量で０.１〜１.８質量％の有機スズ化合物を含んでおり、該有機スズ化合物はオクチル酸第一スズが好ましい。【選択図】 なし
