EVALUATION METHOD AND MANUFACTURING METHOD FOR SHEET CONTAINING OXIDE POWDER, ELECTRONIC PARTS, AND EVALUATION DEVICE AND MANUFACTURING DEVICE FOR SHEET CONTAINING OXIDE POWDER

摘要

PROBLEM TO BE SOLVED: To provide an evaluation method enabling to precisely evaluate a film containing oxide powder, a sheet manufacturing method using the evaluation method, an evaluation device and manufacturing device suitable for the these methods, and ceramic electronic parts with high reliability and productivity.;SOLUTION: This evaluation method comprises a step in which the light intensity of light L passing through the sheet 10 including a film 12 containing predetermined oxide powder is measured by projecting light L with wavelength of λ_Z to a sheet 10, and a step in which information on either of the weight per unit area or the particle diameter of the oxide powder included in the film 12 is obtained based on the measured light intensity. The wavelength of λ_Z is at least within the range greater than 900 nm.;COPYRIGHT: (C)2006,JPO&NCIPI
