Light-emitting device, light source device, and method for manufacturing light-emitting device

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

• providing an intermediate body in which light-emitting elements mounted on first leads of linked bodies, the linked bodies comprising one or more pairs of the first lead and a second lead with a linked portion, and the light-emitting element and the second lead are electrically connected via a conductive member in the one or more pairs;
• supplying a material of a mold resin member in recesses in a casting case;
• inserting the intermediate body into the recesses in which the material of the mold resin member is supplied, and forming the mold resin member configured to directly or indirectly cover the light-emitting elements for each pair of the first lead and the second lead;
• and
• individually separating by cutting off the linked portion of the linked body so as to make the pairs each comprising the first lead and the second lead, wherein,
• in the supplying of the material of the mold resin member in the recess, the casting case has a lens portion opening on a bottom side of the casting case, an inclined portion opening connected from the lens portion opening and spreading and inclined toward an opening side of the casting case, and a fixing portion opening connected from the inclined portion opening toward the opening side of the casting case, and
• in the forming of the mold resin member, the light-emitting element is disposed inside the fixing portion opening.
