Provided are: a condensate which can enhance the tight adhesion between a substrate and an electroconductive pattern formed using an electrocoductive ink, particularly, an ink or paste that contains metal nanoparticles; and a process for manufacturing the same. This condensate is a condensate which is obtained by hydrolytic condensation of an amino-bearing silane coupling agent with a metal alkoxide compound represented by general formula (I) and which comprises M-O repeating units as the main skeleton. R1 nM(OR2)m-n ··· (I) In general formula (I), R1 is a nonhydrolyzable group; R2 is C1-6 alkyl; M is at least one metal selected from the group consisting of Si, Ti, Al, Zr, Li, Na, Ca, Sr, Ba, Zn, B, Ga, Y, Ge, Pb, P, Sb, V, Ta, W, La, Nd and In; m represents the valence of M and is 3 or 4; when m is 4, n is an integer of 0 to 2, while when m is 3, n is an integer of 0 to 1; and in a case where multiple R1 moieties are present, the R1 moieties may be the same or different from each other, while in a case wherein multiple OR2 moieties are present, the OR2 moieties may be the same or different from each other. |
