Light emitting device

A light-emitting device comprising:

• a substrate having an upper surface and comprising a plurality of terminal parts disposed on an upper surface side;
• a light-emitting element having a lower surface and comprising a plurality of electrode parts disposed on a lower surface side, the electrode parts being arranged on the terminal parts;
• and
• a plurality of bonding parts bonding the substrate and the light-emitting element;
• wherein:
• the terminal parts include:
• a central terminal part having a surface in which a first recessed portion is disposed;
• and
• a plurality of peripheral terminal parts at least partially surrounding the central terminal part, each having a surface in which a second recessed portion is disposed;
• the electrode parts include:
• a central electrode part connected to the central terminal part and including a surface in which a third recessed portion is disposed;
• and
• a plurality of peripheral electrode parts at least partially surrounding the central electrode part, each connected to a corresponding one of the peripheral terminal parts, and each having a surface in which a fourth recessed portion is disposed;
• the bonding parts include:
• a central bonding part partially disposed in the first recessed portion and the third recessed portion, and bonding the central electrode part and the central terminal part;
• and
• a plurality of peripheral bonding parts, each partially disposed in a corresponding one of the second recessed portions of the peripheral terminal parts and in a corresponding one of the fourth recessed portions of the peripheral electrode parts, and each bonding a corresponding one of the peripheral electrode parts and the corresponding one of the peripheral terminal parts;
• a center-to-center distance between the second recessed portions of adjacent ones of the peripheral terminal parts differs from a center-to-center distance between the fourth recessed portions of the corresponding adjacent ones of the peripheral electrode parts;
• and
• in a plan view, a center of at least one of the fourth recessed portions does not overlap the corresponding one of the second recessed portions.
