To manufacture a panel body 40 for building with frames in different longitudinal lengths without damaging appearance and an architectural design, using a ceramic system building board 10, in which a standard size is simplified, as a face material.

When the panel body 40 for building with the frames is manufactured by mounting the building board 10, in which vertically stuck brick patterns partitioned by vertical recessed grooves 14 are formed at the lowermost stage of multistage horizontally stuck brick patterns in one surface of a four-sided assembled frame body 20, as the face material, the building board 10 is installed to the frame body 20, after the vertically stuck brick patterns of at least the building board are cut to match the lengths0. when the longitudinal length of the frame body 20 is made shorter than that of the building board 10.
