Semiconductor laser device

A semiconductor laser device comprising:

• a base;
• a semiconductor laser element disposed on the base and having at least one light-emitting point configured to emit laser light;
• a lens having a light input surface facing the at least one light-emitting point in a first direction, a light output surface located on a side opposite to the light input surface in the first direction, a first end surface located on one side in a second direction perpendicular to the first direction, and a second end surface located on the other side in the second direction, and configured to adjust a spread angle of the laser light in a third direction perpendicular to both the first direction and the second direction;
• a first support body having a first surface located on the first end surface side in the second direction and a second surface located on a side opposite to the first end surface in the second direction, and supporting the lens with respect to the base;
• and
• a first bonding member bonding the lens and the first support body, wherein
• the first support body has a first opening portion opened to the first surface and the second surface,
• at least a part of an inner opening of the first opening portion on the first surface side overlaps the first end surface when viewed from the second direction, and
• the first bonding member is continuously disposed in at least a part of a region between the first end surface and the inner opening of the first opening portion and at least a part of a region in the first opening portion.
