1. An ultrasonic diagnostic apparatus for assisting insertion work of a puncture needle into a subject, the ultrasonic diagnostic apparatus comprising:
an ultrasonic probe that is arranged to allow a probe distal end part to be pressed against a body surface of the subject, and configured to acquire an ultrasonic image of an inside of the subject by transmission and reception of an ultrasonic wave;
a laser pointer that is attached to a proximal end side of the ultrasonic probe and configured to emit laser light onto the body surface of the subject to form a predetermined projection image; and
an optical camera that is attached to the proximal end side of the ultrasonic probe and configured to capture an optical image in a plane orthogonal to a sound axis center of the ultrasonic probe, the optical image including an arrangement position of the probe distal end part of the ultrasonic probe, the body surface of the subject and the predetermined projection image formed by the laser light,
wherein the predetermined projection image is configured to guide a target insertion position and a target orientation of the puncture needle when the puncture needle is inserted into the subject, in the optical image acquired by the optical camera.
