Light emitting device and manufacturing method thereof

A light emitting device, comprising:

• a light emitting element;
• a light emitting element container having a concave section for containing the light emitting element and having a plate section;
• electrodes;
• via wiring formed in the plated section;
• and
• a conductive paste layer formed of a conductive paste in which metal particles are dispersed in a solution;
• wherein
• the concave section includes a side surface and a bottom surface almost orthogonal to the side surface;
• the conductive paste layer includes a slanting surface on the side surface and the bottom surface;
• the via wiring is electrically connected to the electrode;
• and
• the conductive paste layer is not formed on an upper surface of the via wiring.
