The present invention relates to a process for producing amino/guanidinothiosulfonic acid, which comprises treating a styrenedivinylbenzene copolymer sulfonate of amino/guanidinoethyl disulfoxide into contact with an alkali, selectively eluting amino/guanidinosulfinic acid, then reacting this product in a non-aqueous solvent in the presence of a base, and passing the reaction product through a weakly acidic cation exchange resin column; in accordance with the present invention, hypotaurine, thiotaurine and the like having a high purity can industrially be produced.
