Manufacturing method of light-emitting device, and light-emitting device

A light-emitting device comprising:

• a mounting substrate having a flat upper surface including a mounting surface, the mounting substrate including a first metal pattern arranged on the upper surface, a second metal pattern arranged on the upper surface inward of the first metal pattern in a plan view, and a third metal pattern arranged on the upper surface outward of the first metal pattern in the plan view;
• a light-emitting element arranged over the mounting surface;
• and
• a sealing member joined to at least the first metal pattern of the mounting substrate via a joining member, the sealing member including a fourth metal pattern with a width greater than a width of the first metal pattern, an outer side of the fourth metal pattern being arranged inward of an outer side of the third metal patten in the plan view, and an inner side of the fourth metal pattern being arranged outward of an inner side of the second metal pattern in the plan view.

A manufacturing method of a light-emitting device, comprising:

• preparing a mounting substrate having a flat upper surface including a mounting surface, the mounting substrate including a first metal pattern arranged on the upper surface, a second metal pattern arranged on the upper surface inward of the first metal pattern in a plan view, and a third metal pattern arranged on the upper surface outward of the first metal pattern in the plan view:
• arranging a light-emitting element over the mounting surface of the mounting substrate;
• applying a bonding material to the first metal pattern;
• and
• joining a sealing member to at least the first metal pattern of the mounting substrate via the bonding material, the sealing member including a fourth metal pattern with a width greater than a width of the first metal pattern, wherein
• the joining of the sealing member includes preparing the sealing member so that the fourth metal pattern includes a thin portion with a smaller thickness than other portions of the fourth metal pattern.
