To provide a material and a sheet for removing an aldehyde that selectively and efficiently remove an aldehyde alone without using activated carbon or impregnated activated carbon.

The material for removing an aldehyde employs silica gel having micropores of diameters of 12 to 100 nm as a support with at least one species of hydrazide compounds supported thereon, and thereby the characteristics of removing an aldehyde and the suppressing of odor resulting from the removed aldehyde can be attained at the same time.
