Light-emitting device and method of manufacturing light-emitting device

A light-emitting device comprising:

• a base structure having a first surface, and a second surface positioned higher than the first surface, the second surface having a rectangular frame shape surrounding the first surface in a top view, the second surface including a first region and a second region;
• one or more light-emitting elements arranged on the first surface;
• an optical member bonded to the base structure so as to at least partially overlap the first surface in the top view;
• a plurality of first adhesive parts formed by curing a first adhesive agent, the first adhesive parts being disposed respectively in the first region and the second region of the second surface at positions between the second surface and the optical member and fixing the optical member to the base structure, the first adhesive parts not being disposed at corners of the rectangular frame shape of the second surface;
• and
• a plurality of second adhesive parts formed by curing a second adhesive agent different from the first adhesive agent, the second adhesive parts being disposed such that a pair of the second adhesive parts are respectively located at both opposite sides of a corresponding one of the first adhesive parts in the first region on the second surface without being in contact with the corresponding one of the first adhesive parts and another pair of the second adhesive parts are respectively located at both opposite sides of a corresponding one of the first adhesive parts in the second region on the second surface without being in contact with the corresponding one of the first adhesive parts, the second adhesive parts not being disposed at the corners of the rectangular frame shape of the second surface, wherein
• in the top view, a virtual first line segment, which connects two points respectively on the first adhesive parts in the first region and the second region, extends across the first surface,
• in the top view, a virtual second line segment, which connects two points respectively on the pair of the second adhesive parts at the both opposite sides of the corresponding one of the first adhesive parts in the first region, does not extend across the first surface,
• in the top view, a virtual third line segment, which connects two points respectively on the another pair of the second adhesive parts at the both opposite sides of the corresponding one of the first adhesive parts in the second region, does not extend across the first surface,
• in the top view, a width of the corresponding one of the first adhesive parts in the first region in a direction parallel to the second line segment is greater than a width of each of the pair of the second adhesive parts at the both opposite sides of the corresponding one of the first adhesive parts in the first region in the direction parallel to the virtual second line segment, and
• in the top view, a width of the corresponding one of the first adhesive parts in the second region in a direction parallel to the third line segment is greater than a width of each of the another pair of the second adhesive parts at the both opposite sides of the corresponding one of the first adhesive parts in the second region in the direction parallel to the virtual third line segment.
