Abstract: According to one embodiment, a stress detection apparatus includes a processor. The processor acquires heartbeat information. The processor calculates a heart rate variability factor from the heartbeat information. The processor detects change of an activity of sympathetic nervous system, based on the heart rate variability factor. The processor detects change of an activity of parasympathetic nervous system, based on the heart rate variability factor. The processor detects presence/absence of a stress state, based on time from detection of the change of the sympathetic nervous system to detection of the change of the activity of the parasympathetic nervous system. The processor acquires outside stimuli. The processor identifies a stressor that has provided the stress state from the acquired outside stimuli, based on timing at which the change of the sympathetic nervous system has been detected if the stress state is detected.
