Abstract
A laser module includes an optical fiber, a laser device, an optical system, a housing, a lead terminal, a conductive wire, and an insulation member. The laser device emits a laser beam. The optical system couples the laser beam, emitted from the laser device, to the optical fiber. The housing includes a base plate on which the laser device is fixed and a side wall that includes an opening. The lead terminal extends from an outside of the housing through the opening of the side wall into the housing. The conductive wire electrically connects a connecting portion of the lead terminal, located within the housing, to the laser device. The insulation member includes a seal portion and an extension portion.
