A hand-written character recognition device including: input unit, having input portion, for successively detecting x-y coordinate points of a hand-written character written on the input portion; vector calculation unit for calculating a vector between the detected x-y coordinate points; angle calculation unit for calculating an angle between the vectors calculated by the vector calculation unit; noise identifying unit for analyzing positional variation of the coordinate points on basis of the calculated vectors and the calculated angles, and identifying coordinate points whose positional variation exceed a predetermined variation range as noise coordinate points; and noise removing unit for removing noise coordinate points from the coordinate points detected by the input unit.
