The invention relates to a ceramic solar board with an air heat insulating layer. A ceramic solar board manufactured before is in a structure of single layer via hole plate, a work media is contained in a via hole, the back surface and the side surface of the work media are adhered to heat insulating materials to prevent heat from losing, and the heat insulating materials limit the service life of a heat collector of the ceramic solar board leading to higher manufacture cost. In the ceramic solar board with multiplayer via holes, the work media is contained in a via hole which is near the southern slope of the ceramic solar board, and air layers in other via holes which are near the back surface or the back surface and the side surface of the ceramic solar board are taken as heat insulating layers to replace the heat insulating materials, thereby the service life of the heat collector of the ceramic solar board is prolonged, and the manufacture cost of the heat collector of the ceramic solar board is lowered.
