PROBLEM TO BE SOLVED: To provide a transparent insulating low melting point glass hardly causing yellowing by the reaction with a silver electrode, suitable for the formation of a dielectric layer and having high transmittance with visible light. SOLUTION: The transparent insulating low melting point glass contains, by weight, 2-15% SiO<SB>2</SB>, 20-35% B<SB>2</SB>O<SB>3</SB>, 1-7% Al<SB>2</SB>O<SB>3</SB>, 35-44% PbO, 10-25% BaO and 0-3% at least one or more kinds of alkaline earths selected from CaO, MgO and SrO and further contains 0.1-0.5% CoO and 0.01-1% CeO<SB>2</SB>as essential components, wherein CoO+CeO<SB>2</SB>is 0.1-1% and CoO/CeO<SB>2</SB>is 0.5-20, and contains substantially no CuO, TiO<SB>2</SB>, ZrO<SB>2</SB>, La<SB>2</SB>O<SB>3</SB>and Ta<SB>2</SB>O<SB>5</SB>. All light transmittance and straight light transmittance in 25μm thickness are respectively≥80% and≥70%. COPYRIGHT: (C)2006,JPO&NCIPI
