## Abstract

A light-emitting apparatus includes a substrate warped as a whole of which a central portion is most highly raised; a light-emitting device mounted on the central portion of the substrate; a support member disposed on the substrate so as to surround the light-emitting device; and a frame body disposed on the support member so as to surround the light-emitting device, the frame body including part connected to the support member and part not connected to the support member, the part not connected to the support member being left spaced from an upper surface of the substrate. Moreover, the light-emitting apparatus is constituted so that a level of a lower surface of the light-emitting device is higher than a level of a lower surface of the frame body.

## Claims

### Claim 1

A light-emitting apparatus, comprising:
a substrate warped as a whole of which a central portion is most highly raised;
a light-emitting device mounted on the central portion of the substrate;
a support member disposed on the substrate to surround the light-emitting device; and
a frame body disposed on the support member so as to surround the light-emitting device, the frame body including part connected to the support member and part not connected to the support member, the part not connected to the support member being left spaced from an upper surface of the substrate,
a level of a lower surface of the light-emitting device being higher than a level of a lower surface of the frame body.

### Claim 2 (depends on 1)

The light-emitting apparatus according to claim 1,
wherein the substrate is asymmetrical about a center of the substrate as viewed in section.

### Claim 3 (depends on 1)

The light-emitting apparatus according to claim 1,
wherein the substrate is obtained by integrally firing a plurality of laminated ceramic layers, and a lower surface of the substrate is provided with a pair of metallization layers electrically connected to the light-emitting device, and
the substrate has thereinside an electrical conductor for electrically connecting the metallization layers to the light-emitting device, and part of the electrical conductor connected to one of the pair of metallization layers is composed of a through conductor, and part of the electrical conductor connected to another one of the pair of metallization layers is composed of a through conductor and an interlayer conductor disposed along an interlayer within the substrate.

### Claim 4 (depends on 3)

The light-emitting apparatus according to claim 3,
wherein the interlayer conductor extends from a region in overlapping relation to the light-emitting device to a region in non-overlapping relation to the light-emitting device.

### Claim 5 (depends on 1)

The light-emitting apparatus according to claim 1,
wherein, in a region surrounded with the support member and the frame body, a sealing member extends from an upper surface of the light-emitting device to a space between the lower surface of the frame body and the upper surface of the substrate.
