A fixing jig includes a pedestal including a placing surface on which a columnar honeycomb structure is placed, holding members fixed to the pedestal and configured to hold a side surface of the honeycomb structure placed on the placing surface, and drawing and fixing members fixed to the pedestal and configured to draw and fix the surface on the pedestal side in the outer circumferential portion of a mask placed on the honeycomb structure. Consequently, the fixing jig can fix the honeycomb structure and the mask aligned with each other and is less likely to hinder the alignment of the mask.
