Claims

[Scope of Claim for Utility Model Registration] An optical/electrical conversion module comprising a light emitting element and a light receiving element housed in a transparent resin, and a jacket portion provided at the end of a coated fiber cable, the tip of the fiber cable. In an optical plug provided with a ferrule for positioning a surface, the ferrule is provided with a guide groove having a claw portion and a fixing member attachment portion to which a fixing member is attached, and the fiber cable is connected to the fiber cable while the jacket portion is covered. an optical plug having a structure in which the optical plug is inserted into the guide groove in this state to engage the claw part and the jacket part, and the fixing member is attached to the fixing member attachment part from above the fiber cable inserted into the guide groove. .
