According to one embodiment, an ultrasonic diagnostic apparatus comprises an ultrasonic probe, image generation circuitry, an optical probe, at least one integrated solid-state image sensor and analysis circuitry. The image generation circuitry generates an ultrasonic image by using the ultrasonic wave. The an optical probe is integrally provided with the ultrasonic probe and including at least one light emission circuitry to apply light in an absorption wavelength band of a biological component from a surrounding of the ultrasonic transmission/reception surface onto the inside of the object and a plurality of optical detection circuits to detect an intensity of light having a specific wavelength which is applied from the at least one light emission circuitry and diffused/reflected by the inside of the object. The analysis circuitry is configured to analyze a change in the light intensity detected by the each optical detection circuit.
