Abstract
A filtration plate (1, 1′) for a particle filter which serves to separate particles from an exhaust gas flow of an internal combustion engine is composed of a gas-permeable carrier material which is coated with sintered metal powder, and has a surface region (2) which extends substantially in one plane and on which at least one spacer element (3, 3′) is situated. The at least one spacer element (3, 3′) has an inner elevation (9) or depression (9′) which extends away from the surface region (2) in one direction, and an outer depression (10) or elevation (10′) which surrounds the inner elevation (9) or depression (9′) at least partially and extends away from the surface region (2) in the opposite direction to the inner elevation (9) or depression (9′).
