Abstract
A light emitting device includes a first support member having an outer circumferential lateral surface and a first through-hole, a light-transmissive member including a fluorescent material and disposed in the first through-hole, a second support member having an inner circumferential lateral surface and a second through-hole and a light emitting element disposed below the first support member. At a temperature higher than a first temperature in a range of 200° C. to 800° C., an outer dimension of the first support member is smaller than an inner dimension of the second support member. At room temperature, the outer dimension of the first support member without being fixed is greater than the inner dimension of the second support member without being fixed. The first temperature is a temperature at which a magnitude correlation between the outer dimension of the first support member and the inner dimension of the second support member is reversed.
