Cover glass for light emitting diode package, sealed structure, and light emitting device

When local heating by use of laser sealing or the like is applied, the bonding strength between glass substrates and a sealing layer is improved to provide an electronic device having increased reliability. An electronic device includes a first glass substrate, a second glass substrate, and a sealing layer to seal an electronic element portion disposed between these glass substrates. The sealing layer is a layer obtained by locally heating a sealing material by an electromagnetic wave, such as laser light or infrared light, to melt-bond the sealing material, the sealing material containing sealing glass, a low-expansion filler and an electromagnetic wave absorber. In the first and second glass substrates, each reacted layer is produced to have a maximum depth of at least 30 nm from an interface with the sealing layer.
