Claim 9:
10. A method for producing a bonded structure, the method comprising:
temporarily fixing a first bonding target material and a second bonding target material to each other with a temporary fixing composition disposed between the first bonding target material and the second bonding target material; and
firing the temporarily fixed bonding target materials to thereby bond the bonding target materials to each other,
wherein, the temporary fixing composition includes:
a first organic component having a viscosity of 40 mPa·s or less at 25° C. and a boiling point of 200° C. or lower; and, a second organic component having a viscosity of 70 mPa·s or greater at 25° C. and a boiling point of 210° C. or higher,
wherein the temporary fixing composition is substantially free of an organic polymer compound.
