Embodiment approach
[0109] As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, Various changes are possible in the range which does not deviate from the summary of this invention.
[0110] For example, the above embodiments exemplify multilayer ceramic capacitors as the multilayer ceramic electronic components of the present invention, but the multilayer ceramic electronic components of the present invention are not limited to multilayer ceramic capacitors, and can of course be applied to multilayer ceramic substrates and the like.
Embodiment 1
[0114] First, a butyral resin-containing dielectric paste for forming a ceramic green sheet using a butyral resin (polyvinyl butyral) as an organic binder was prepared.
[0115] Preparation of Dielectric Paste Containing Butyral Resin
[0116] Prepare BaTiO 3 Ceramic powder, polyvinyl butyral (PVB) as an organic binder, and methanol as a solvent. Then, 10 parts by weight of the organic binder and 150 parts by weight of the solvent were weighed with respect to 100 parts by weight of the ceramic powder, and kneaded and slurried by a ball mill to obtain a butyral resin-containing dielectric paste.
[0117] Fabrication of Ceramic Green Sheets Containing Butyral Resin
[0118] The above-mentioned dielectric paste was applied to a predetermined thickness on a PET film by a doctor blade method, and dried to form a butyral resin-containing ceramic green sheet having a thickness of 1.5 μm after drying.

Embodiment 2
[0127] Compatibility test of solvent and ceramic green sheet containing acrylic resin (50°C, dipping)
[0128] Except using acrylic resin as the organic binder, operate in the same manner as in Example 1 to make a dielectric paste containing acrylic resin and a ceramic green sheet containing acrylic resin. Compatibility test of green sheet (50°C, immersion).
[0129] In addition, in Example 2, various solvents shown in Table 2 below were used as solvents, and photographs of acrylic resin-containing ceramic green sheets dipped in the respective solvents were shown in each figure described in Table 2, respectively.
