Title: OPTICAL CONNECTOR AND PHOTOACOUSTIC WAVE EMISSION DEVICE
Abstract:
Provided is an optical connector that can improve insertability into a connection part of an item to which the optical connector will be connected. Also provided is a photoacoustic wave emission device that uses said optical connector. The present invention comprises: an optical fiber (10) that has a ferrule part (11) provided at one end thereof; and a cylindrical connection member (12) that is formed in a cylindrical shape into which the optical fiber (10) is inserted, one end section of the cylindrical connection member (12) having the ferrule part (11) positioned within the cylinder, and the other end section having the other end of the optical fiber drawn out therefrom, wherein the ferrule part (11) has a protrusion (11c) having a protrusion direction in a direction that is perpendicular to a length direction of the cylindrical connection member (12), and an O-ring (15) is provided contacting a surface of the protrusion (11c), said surface being on an outer side in the length direction of the cylindrical connection member (12).
