PURPOSE: To make a toilet foldable, compact and portable and further easy to assemble for use by coupling integrally a toilet body formed by assembling a sheet of board into a cylinder and a bag for housing excrement with an opening peripheral part of the bag adhered to the inside of the toilet body.

CONSTITUTION: A toilet body A is formed of a sheet of hard board, a thin synthetic resin plate or the like having an appropriate thickness. A front wall 1 connected foldably at an upper end with a semi-arched shielding plate 11, a right side wall 2 connected foldably at an upper end with a seat plate 21, a rear wall 3 with a low shielding plate 31 protruding from an upper end, a left side wall 4 connected foldably at an upper end with a seat plate 41, and a margin 5 are formed successively through bending lines 6. An excrement housing bag B is made of a synthetic resin such as polypropylene or polyethylene, has an appropriate length, and further a length of an opening peripheral part just the same as that (peripheral length) of an inside wall surface of the toilet body A formed in a cylinder.
