PROBLEM TO BE SOLVED: To provide a charcoal-containing cushion material expressing good body pressure-dispersing property while having charcoal particles attached by a binder. SOLUTION: In the charcoal-containing cushion material 10 containing polyurethane foam in which charcoal particles are attached to the surface part of the foam, charcoal particles are attached to recurring surfaces of recessed parts and protruded parts. In that case, it is preferable that charcoal particles are attached to only protruded parts or only recessed parts so as not to continue whole recurring area of recessed parts and protruded parts.
