Abstract: In a biological information detection device, a frequency characteristic indicating a relation between a frequency and an intensity is acquired with respect to each of a plurality of biological signals input respectively from a plurality of biological activity sensors arranged at a plurality of positions different from each other to detect a biological activity of a person. A synthetic frequency characteristic indicating the relation between the frequency and the intensity is obtained by synthesizing a plurality of frequency characteristics acquired from the plurality of biological signals. Biological information on the biological activity is calculated based on the synthetic frequency characteristic.
