1. A porous composite comprising:
a porous base material; and
a porous collection layer formed on said base material,
wherein said base material has a honeycomb structure whose inside is partitioned by a partition wall into a plurality of cells extending in a longitudinal direction,
said plurality of cells include a plurality of first cells whose one ends in the longitudinal direction are sealed, and a plurality of second cells whose other ends in the longitudinal direction are sealed, said plurality of first cells and said plurality of second cells being arranged alternately,
said collection layer covers inner surfaces of said plurality of first cells,
an overall Sa that is an arithmetical mean height Sa indicating a surface roughness of a surface of said collection layer in said plurality of first cells is greater than or equal to 0.1 μm and less than or equal to 12 μm, and
an overall mean thickness that is a mean thickness of said collection layer in said plurality of first cells is greater than or equal to 10 μm and less than or equal to 40 μm.
