o make paper from non-wood fiber is important because of protection of forest resources environmentally. Moreover; if paper can be made from familiar plants; it will be useful for both effective utilization of resource and environmental education. In this research; corn shuck and leaf; and half-split chopsticks were soaked into the bleaching agent on market in Japan; with changing concentration of the agent and soaking time; and pulp was manufactured. Relations between the quantity of the agent and the soaking time; or pulp yield were examined. For corn shuck and leaf; the yield decreased linearly with increase of the agent or soaking time; in general. But; for the case of applying much shuck; the relation showed maximum curve. If the agent was very less; paper had yellowish. If the agent was increased; the paper became whiter; but orange tint slightly. Compared with papers on market; created papers had smaller apparent specific gravity and air resistance; and were thicker. The sensory test was conducted using both of created papers and papers on market. Homogeneity impression was associated with many impression factors. Papers which were judged as homogeneous had impressions of high intensity; high artificial degree and not-warmth. Papers with heterogeneous or rough impression brought high ventilation impression for subjects. Individual differences of impression point relevant to visual and tactile were apparently smaller than those which might be regarded as physical properties; in general.
