Abstract: An analysis threshold determination device includes a threshold determination unit for determining a pair of or plural pairs of thresholds used for analysis in accordance with a pair of thresholds generated by a calculation unit and a count value output from a. pulse count unit. The calculation unit repeatedly generates a new pair of thresholds in which at least one of the pair of thresholds is changed every time the pulse count unit counts the pulse until reaching a predetermined value. The threshold determination unit chooses a class of a measure of central tendency according to a frequency distribution defining each pair of thresholds generated as a class and the count value output from the pulse count unit as a frequency. The threshold determination unit determines a pair of or plural pairs of thresholds corresponding to a class of a predetermined range from the class of measure of central tendency.
