According to the optical probe of an aspect of the present invention, the flexible and optically transparent partition wall separates the imaging core lumen and the guidewire lumen, and the pressure increasing/decreasing port increases/decreases the pressure inside the imaging core lumen that is at a proximal part of the imaging core lumen. It is therefore possible to advance the probe along the guidewire as far as an affected area, and by pulling back the guidewire to a handle portion to push out the imaging core to the distal end portion, it is possible to observe a distal part and obtain an image without guidewire artifacts.
