Abstract
A light-emitting device includes: a semiconductor layer including a first conductive contact layer, a first conductive cladding layer, an active layer, a second conductive cladding layer, a second conductive contact layer and a resin block layer in this order; a first electrode in contact with the first conductive contact layer; and a second electrode in contact with the second conductive contact layer. The second conductive contact layer includes a first opening at least in a region facing the first electrode. Moreover, the resin block layer includes a plurality of second openings communicated with the first opening, and the first opening has an air gap.
