<p><P>PROBLEM TO BE SOLVED: To provide a lead-free and ruthenium-free conductive material which can be substituted for Pb<SB>2</SB>Ru<SB>2</SB>O<SB>6.5</SB>, as a conductive material for forming the thick film resistor of a relatively high resistivity region, to provide a paste for the thick film resistor, and to provide a manufacturing method of the paste. <P>SOLUTION: The conductive material for use in formation of the thick film resistor includes a compound oxide consisting of La<SB>1-x</SB>Sr<SB>x</SB>MnO<SB>3</SB>(x is a substitution ratio) in which a part of La of LaMnO<SB>3</SB>is substituted with Sr. In this case, it is preferable that the substitution ratio x is 0.2 to 0.5. Also, the paste for the thick film resistor is obtained by kneading the conductive material La<SB>1-x</SB>Sr<SB>x</SB>MnO<SB>3</SB>(x is a substitution ratio) in which a part of La of LaMnO<SB>3</SB>is substituted with Sr, a glass material and a vehicle. Thus, the lead-free and ruthenium-free thick film resistor having a relatively high resistance value is manufactured using an inexpensive material. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
