PROBLEM TO BE SOLVED: To improve the reliability and productivity of a small-sized spark plug by creating a glass powder for forming a resistor, having high ability to absorb high frequency noise radio waves and properly functioning as block particles, in order to form a resistor efficiently absorbing the high frequency noise radio waves. SOLUTION: The glass powder for forming a resistor contains, by mol, 40-60% SiO<SB>2</SB>, 28-40% B<SB>2</SB>O<SB>3</SB>, 1-20% of Li<SB>2</SB>O+Na<SB>2</SB>O+K<SB>2</SB>O, 0.1-20% CaO, and 0-7% BaO, as a glass composition.
