A seat belt wearing detection device includes: a tongue unit supported by a seat belt; a buckle unit into which the tongue unit is inserted and held; a wearing detection unit that detects an insertion and holding state; a seat belt side communication unit that transmits a detection result; a control unit that determines a wearing state based on the detection result and controls the seat belt side communication unit; power supply means for supplying electric power to the seat belt side communication unit; and a vehicle side device that performs radio communication with the seat belt side communication unit to receive the detection result. The power supply means includes a power supply section, a power storage section, and a charging section. The power supply section charges the power storage section by supplying electric power to the charging section when the seat belt is in a housed state. |
