An insulating paste comprises a glass component composed of SiO2, B2O3 and K2O as xSiO2-yB2O3-zK2O, where x, y and z (% by weight) fall within the area surrounded by points A (x=65, y=35, z=0), B (x=65, y=20, z=15), C (x=85, y=0, z=15) and D (x=85, y=15, z=0), and an organic vehicle. The insulating layer made of the paste has a low dielectric constant and excellent insulating properties.
