Estimating the term…
A ceramic member in which the metal layers with high void ratio are sufficiently sintered to lower a residue of resin is produced. The method for manufacturing a ceramic member which comprises a step of forming a stacked compact from a plurality of metallic paste layers containing a metal component M1 that are stacked one on another via ceramic green sheets, and a step of firing the stacked compact, wherein at least one of plural metallic paste layers is formed as a second metallic paste layer that has the mass percentage X higher than that of the metallic paste layer that adjoin therewith in the stacking direction and a ceramic powder is contained in the second metallic paste layer in the step of forming the stacked compact, the mass percentage X being the proportion of the metal component M1 to the total metal content in the metallic paste layer.
A ceramic member having a three-layer structure comprising a metal layer containing the metal component M1, a lump containing layer that include more voids than the metal layer and a plurality of ceramic lumps dispersed while being separated from each other by the voids, and a ceramics layer sandwiched by the metal layer and the lump containing layer.
