Document Type and Number:
WIPO Patent Application WO/2023/090312
Kind Code:
A1
Abstract:
Provided is a laminated sheet manufacturing method which can easily reduce thickness non-uniformity. A manufacturing method of a laminated sheet 20 according to the present invention comprises: a ceramic green sheet manufacturing step S1 for molding slurry including ceramic powder into a sheet shape and manufacturing ceramic green sheets 21; an internal electrode printing step S2 for printing internal electrodes 12 on the ceramic green sheets 21; an insulating paste placement step S3 for placing an insulation paste 14b, of which a storage elastic modulus E' is 1.0 MPa to 100 Mpa at 80°C and a frequency of 1 Hz, in an area in which the internal electrodes 12 are not printed on the same surface as a surface on which the internal electrodes 12 are printed on the ceramic green sheets 21; a lamination step S4 for laminating the ceramic green sheets 21 on which the internal electrodes 12 are printed and the insulation paste 14b is placed; and a press step S5 for pressing the laminated ceramic green sheets 21 and manufacturing the laminated sheet 20.
