mobile terminal (1), the mind that divides the biological signal to the waveform of a constant interval Wire No. splitting section (142) for each of the predetermined interval divided by the ECG signal splitting portion waveform, a plurality calculated R-R interval that indicates the distance between the wave adjacent R and R-wave, calculated R-R interval calculating unit for calculating an average value of a plurality of R-R interval and (144), the average using the average value of R-R intervals calculated by the R-R interval calculator for each waveform of the predetermined intervals Since was to have the candidate waveform selection section that selects a plurality of waveforms at regular intervals corresponding to the average value in the vicinity of indicating the frequency maximum of the values and (145), it is possible to generate an accurate representative waveform data.携帯端末(1)は、生体信号を一定間隔の波形に分割する心電信号分割部(142)と、心電信号分割部によって分割された一定間隔の波形毎に、隣り合うR波とR波との間の間隔を示すR-R間隔を複数算出し、算出した複数のR-R間隔の平均値を算出するR-R間隔算出部(144)と、R-R間隔算出部によって一定間隔の波形毎に算出されたR-R間隔の平均値を用いて平均値の頻度が極大値を示す付近の平均値に対応する一定間隔の波形を複数選択する候補波形選択部(145)とを有することとしたので、精度の良い代表波形データを生成できる。
