An object of the present invention is to provide a building large porcelain panel that prevents the efflorescence. As the solutions, a building large porcelain panel according to the present invention is formed by kneading a raw material formulation containing, as a main material, a refractory aggregate, a glassy raw material, and cement, and subjecting the raw material formulation to molding and then firing, wherein the building large porcelain panel has a Na20 content of 1 mass% or less in an entire chemical-component composition of the building large porcelain panel fired. In addition, the building large porcelain panel has a Na20 content of 1% or less and containing 0.5 to 7% of BaO and 0.5 to 8% of B203 (12% or less of the BaO and the B 20 3) at mass-based chemical component values.
