PURPOSE:To obtain resin housing panel, in which burr can be uniformly cut so as to make the burr flush with the edge face and the edge face having the burr developed therein can be finished fairly only by moving a cutter or the like along a flat plane. CONSTITUTION:Resin housing panel 1 is made by blow-molding thermoplastic plastic and has hollow double wall structure. A portion, which is divided by burrs 4, along one burr 4 is turned into a flat surface 5 nearly normal to the burrs 4. A portion, which is divided by the burrs 4, along the other burr 4 is turned into an inclined surface 6, between which and the burr 4 an obtuse angle is made. |
