摘要： A method of manufacturing ceramics includes: placing, on a base material, a first slurry in which a metal oxide powder is dispersed; applying a magnetic field to the first slurry to solidify the first slurry, thereby forming an under coat layer made of a first compact; placing, on the under coat layer, a second slurry containing a metal oxide powder constituting the ceramics; applying a magnetic field to the second slurry to solidify the second slurry, thereby forming a second compact to obtain a laminated body of the second compact and the under coat layer; and obtaining the ceramics made of the second compact by removing the under coat layer from the laminated body of the second compact and the under coat layer and then sintering the second compact, or sintering the laminated body of the second compact and the under coat layer and then removing the under coat layer.
