Insulating paste
 The invention provides an insulating paste, comprising: an organic vehicle containing an organic binder, a photo-polymerization initiator and a photosetting monomer; and a silicate glass powder having a softening point in a range of about 700.degree. C. to 1,050.degree. C. and having an average particle size in a range of about 0.1 to 5.0 .mu.m, said silicate glass powder being dispersed into said organic vehicle. Preferably, the silicate glass powder of the above insulating paste comprises a composition represented by xSiO.sub.2 -yB.sub.2 O.sub.3 -zK.sub.2 O where x+y+z is 100 parts by weight and the values z, y and z are on lines or within a region enclosed by lines passing through four points A(65, 35, 0), B(65, 20, 15), C(85, 0, 15) and D(85, 15, 0) on a ternary diagram thereof.
