A coating apparatus includes: a supply frame for supplying slurry into channels from one end of a honeycomb substrate; and a blower for evacuating a wind box. An annular resistive member is attached to the circumference of the opening of the wind box, and the honeycomb substrate is arranged, with a spacer placed on the resistive member. When the blower is operated and the slurry is supplied, the coat width of the slurry coated on the inner surfaces of the channels in an outer circumferential area is less than the coat width of the slurry coated on the inner surfaces of the channels in a center area.
