Support material powder comprising:
- a particulate support material, wherein
- the support material comprising:
- at least one member selected from the group consisting of low molecular weight saccharides, polyvinyl alcohols, and polyalkylene glycols;
- non-water-soluble cellulose fibers;
- and
- a water-soluble cellulose derivative.

A method for producing a three-dimensional object comprising:
- a first step of forming a shaped substance containing a structure portion forming a three-dimensional object and a support portion supporting the structure portion;
- and
- a second step of removing the support portion from the shaped substance by bringing the shaped substance into contact with a liquid containing water to form the three-dimensional object, wherein
- in the first step, the support portion is formed using the support material comprising:
- at least one member selected from the group consisting of low molecular weight saccharides, polyvinyl alcohols, and polyalkylene glycols;
- non-water-soluble cellulose fibers;
- and
- a water-soluble cellulose derivative.
