A pulse wave detection device detects pulse wave data from a pulse wave obtained from a user. The pulse wave detection device includes: a pulse wave detection unit detecting the pulse wave data from the pulse wave a pulse wave derivative unit calculating velocity plethysmogram data by temporally deriving the pulse wave data a component extraction unit extracting maximum and minimum values in a current first time range of the velocity plethysmogram data, while shifting the current first time range in a time axis direction, the extraction being repeated in a next current first time range a component ratio calculation unit calculating a component ratio the maximum and minimum values extracted for each current first time range and a noise segment determination unit determining, as a noise segment, a segment in which component ratios calculated by the component ratio calculation unit are temporally inconstant.
