We originally devised a kanji character constructive test in order to study the nature of agraphia and administered it to the aphasic patient with agraphia who also had severe difficulty in copying. Additionally we administered the test to the six aphasic patients with the poorer performance in writing. The responses of the patients were classified into the six categories : (1) no response (2) the selectional error (I) (more than 50 %) (3) the selectional error (II) (less than 50%) (4) the positional error (5) the correct response with repeating approach (conduite d'approchè) (6) the immediate correct response.     The result showed that the patient with severe difficulty in copying had a marked error of position compared with the other patients.
