An optical connector to be connected to an optical plug holding optical fibers includes: a light-emitting element; a light-receiving element; and sleeves that optically connect the light-emitting element and the light-receiving element to optical fibers of the optical plug, respectively, in which a transmission sleeve and a reception sleeve are connected to each other via a link section to form a sleeve unit. The sleeve unit is secured by press-fitting the link section into a connector body. A stress caused by the press fitting is not exerted to the transmission sleeve and the reception sleeve, so that the optical functions (optical properties) of the sleeves can be prevented from being compromised by the stress.
