It is possible to acquire analysis information pertaining to a customer's commodity acquisition behavior with high accuracy by discriminating whether a subject of an action of reaching out to a display shelf area is a store employee or a customer. The personal behavior analysis device includes: an image analyzer that analyzes captured images around a display shelf area, detects a person staying in front of a display shelf area, and acquires analysis information pertaining to physical states of the person; an access action detector that detects an access action, based on the analysis information; a behavior determiner that determines whether or not the access action corresponds to a prescribed behavioral pattern based on access action occurrence circumstances; and an analysis information generator that selects the access action and generates analysis information pertaining to the access action occurrence circumstance.
