A sealed body in which sealing is uniformly performed is provided. A light-emitting module in which sealing is uniformly performed is provided. A method of manufacturing the sealed body in which sealing is uniformly performed is provided. The sealed body comprises a first substrate alternately provided with a high-reflectivity region with respect to the energy ray and a low-reflectivity region with respect to the energy ray so as to overlap with a sealant surrounding a sealed object, and a second substrate capable of transmitting the energy ray. The sealed object is sealed between the first substrate and the second substrate by heating the sealant with irradiation with the energy ray through the second substrate.
