An object of the present invention is to provide a lamp unit for a vehicular headlamp and a vehicular headlamp, by which it is possible to diffuse left and right ends of a high-beam light distribution pattern further to the left and right. An inner reflecting surface reflects light from a first light-emitting element as reflected light onto a lens. The lens emits the reflected light in a diffused light distribution pattern toward a front of a vehicle. An edge of a diffused light distribution pattern on an outer side of the vehicle is located further to an outer side of the vehicle than an edge of a first partial light distribution pattern on the outer side of the vehicle. As a result, left and right ends of an overall high-beam light distribution pattern can be diffused further to the left and right.
