The present invention provides a honeycomb filter capable of effectively suppressing an increase in pressure loss associated with accumulation of particulate matter. This honeycomb filter is provided with: a columnar honeycomb structure section (4) having porous partition walls (1) disposed so as to surround a plurality of cells (2) that form fluid flow paths extending from a first end surface (11) to a second end surface (12); and a sealing part (5) disposed at the opening of each cell (2) on the first end surface (11) side or the second end surface (12) side, and the partition wall (1) is configured such that the average number of branches of pores present on the outermost surface of the partition wall (1) is more than 7.5 and less than 9.0. 本发明提供能够有效地抑制粒子状物质堆积所伴随的压力损失上升的蜂窝过滤器。该蜂窝过滤器具备：柱状的蜂窝结构部(4)，其具有多孔质的隔壁(1)，该隔壁(1)配置成包围多个隔室(2)，该多个隔室(2)形成从第一端面(11)延伸至第二端面(12)的流体流路；以及封孔部(5)，其配设于各隔室(2)的第一端面(11)侧或第二端面(12)侧的开口部，隔壁(1)构成为：在该隔壁(1)的最外表面所存在的气孔的平均分支数超过7.5且小于9.0。
