According to one embodiment, an LED module includes a board, an interconnection and an LED package. The interconnection is formed on an upper surface of the board. The LED package is mounted on the board. The LED package includes first and second lead frames disposed to be apart from each other, and connected to portions of the interconnection insulated from each other. The LED package includes an LED chip provided above the first and second lead frames. The LED chip has one terminal connected to the first lead frame and another terminal connected to the second lead frame. In addition, the LED package includes a resin body covering an upper surface, portions of a lower surface and an edge surface of each of the first and second lead frames, also covering the LED chip, but exposing remaining portions of the lower surface and the edge surface. And, an appearance of the resin body is an appearance of the LED package.

According to one embodiment, an LED package includes first and second lead frames spaced from each other, and an LED chip. Each of the first and second lead frames includes a base portion and a plurality of extending portions extending from the base portion. A part of a lower surface of the base portion, side surfaces of the base portion, lower surfaces of the extending portions and side surfaces of the extending portions are covered by resin. A remaining part of the lower surface of the base portion and tip surfaces of the extending portions are not covered by resin. The part of the lower surface of the base portion includes a first edge of the first lead frame and a second edge of the second lead frame. The first edge and the second edge are opposed each other.

A light emitting device includes: a light emitting element; a first lead including a die pad portion at its one end portion, the light emitting element being bonded to the die pad portion; a second lead with its one end portion being opposed to the one end portion of the first lead; and a resin molded body including a recess with at least part of the die pad portion being exposed to the bottom thereof so that emission light from the light emitting element can be emitted upward, a lower surface with at least part of the lower surface of the first lead and at least part of the lower surface of the second lead being exposed thereto, and a lateral surface with at least part of the lateral surface of the die pad portion being exposed thereto, the resin molded body embedding the first lead and the second lead so that the other end portion of the first lead and the other end portion of the second lead are projected in directions opposite to each other. The at least part of the lateral surface of the die pad portion which is exposed is located on a first plane which is generally coplanar with the lateral surface of the other end portion of the first lead and the lateral surface of the other end portion of the second lead.
