1. A method for sintering a ceramic, the method comprising:
forming a layer comprising a carbon powder on a surface of a ceramic article consisting of a non-sintered ceramic to thereby prepare a carbon powder-containing laminated layer, and
irradiating with a laser a surface of the carbon powder-containing laminated layer to sinter the non-sintered ceramic located under an irradiated area of the carbon powder-containing laminated layer,
wherein the carbon powder in the carbon powder-containing laminated layer at an irradiated part is removed after irradiating, and
wherein the carbon powder is of graphite, and a thickness of the carbon powder-containing laminated layer is in a range from 100 nm to 10 μm.
