An occupant sensor device includes a sensor body unit disposed in a base part of a seat in a vehicle, and an occupant detection device. The sensor body unit is divided into at least two parts, such as a first sensor part and a second sensor part, where the first sensor part is positioned in front of the second sensor part. Based on a capacitance between the sensor body unit and a vehicle body, the occupant detection device detects an occupant type of an occupant that is seated on the seat. In particular, the occupant detection unit is able to detect the occupant type based on a first capacitance provided by the first sensor part, a second capacitance provided by the second sensor part, and a total capacitance, which is a total of the first capacitance and the second capacitance.
