The light-emitting element group includes a plurality of first light-emitting elements and a plurality of second light-emitting elements that are arrayed in a planar manner to form a light-emitting element surface. The first wire extends in a direction parallel to the light-emitting element surface, has a region overlapping with the plurality of first light-emitting elements and a region overlapping with the plurality of second light-emitting elements as viewed from a direction perpendicular to the light-emitting element surface, is electrically connected to the plurality of first light-emitting elements, and is not electrically connected to the plurality of second light-emitting elements. The second wire extends in a direction parallel to the light-emitting element surface, has a region overlapping with the plurality of first light-emitting elements and a region overlapping with the plurality of second light-emitting elements as viewed from a direction perpendicular to the light-emitting element surface, is electrically connected to the plurality of second light-emitting elements, and is not electrically connected to the plurality of first light-emitting elements.

摘要： A light-emitting device includes a base structure, a light-emitting element, an optical member, and first and second adhesive parts. The first adhesive parts are disposed in first and second regions of a second surface of the base structure. The second adhesive parts are located at both opposite sides of the first adhesive part without being in contact with the first adhesive part. In the top view, a virtual first line segment, which connects two points respectively on the first adhesive parts in the first and second regions, extends across a first surface of the base structure. A virtual line segment, which connects two points respectively on the second adhesive parts at the both opposite sides of the first adhesive part, does not extend across the first surface. A width of the first adhesive part along the line segment is greater than a width of the second adhesive part.

摘要： A light emitting device includes: at least one semiconductor laser element; a submount; and a base portion having a mounting surface. The submount includes: a first lateral face being located at a side of an exiting lateral surface of the semiconductor laser element, the first lateral face intersecting the upper face of the submount, and the first lateral face being above and separated from the mounting surface; a lower face being set back inside of the submount relative to an edge at which the upper face and the first lateral face intersect in a top view; and a second lateral face being located at the same side as the first lateral face and intersecting the lower face. A portion of a bonding material protrudes from the lower face and extends outward of an edge at which the lower face and the second lateral face intersect.

摘要： An optical module includes: amounting substrate; a support block on which the mounting substrate is mounted; and a stem having a support surface to support the support block, the stem having a pedestal portion with a tip face in a protruding direction and with an upper surface spreading along the protruding direction; a relay board on the upper surface; a connection block fixed to the tip face; and wires connecting the support block and the mounting substrate to the connection block. The connection block has a surface made of a conductor. The connection block has a first bonding surface facing the same direction as the tip face of the pedestal portion and a second bonding surface facing the same direction as the upper surface. The wires include first and second wires having their ends bonded to the first and second bonding surface, respectively.

摘要： A dielectric substrate has a first surface including a first terminal connector and a second terminal connector located along a first side surface. A recess is between the first terminal connector and the second terminal connector. The recess has a first inner surface continuous with the first terminal connector, a second inner surface continuous with the second terminal connector, and a bottom surface between the first inner surface and the second inner surface. The first terminal connector has first wettability with a bond on its surface, and a first region has second wettability with the bond on its surface lower than the first wettability.
