Expedient and sensitive detection of a detection target substance is enabled in target substance detection that detects the detection target substance at a sensor portion provided within a flow channel. A detection target substance detecting method for a detecting detection target substance which may be contained in a liquid sample emits ultrasonic waves that propagate in a direction transverse to a flow channel when the liquid sample flows within a ultrasonic wave emission region at which ultrasonic waves can be emitted, to concentrate the detection target substance at a wall surface of the flow channel toward the side of the sensor portion and to detect the detection target substance. |
