- the light reflecting layer 3 is preferably formed of glass ceramics. In this case, the light reflectance can be further increased, and the adhesiveness with the aluminum nitride substrate 2 can be further increased.
- the method for forming the light reflecting layer 3 is not particularly limited, and examples thereof include a screen printing method and a green sheet laminating method.
- a high viscosity paste prepared by adding a resin binder and a solvent to the glass ceramic powder and kneading is used with a screen printing machine. This can be done by printing on the aluminum nitride substrate 2.

Subsequently, the prepared slurry is formed into a green sheet using a sheet forming machine such as a doctor blade. Next, the obtained green sheet is punched into the shape of the light reflecting layer 3 and laminated on the aluminum nitride substrate 2 by pressure bonding.

More specifically, the through holes 107 a and 107 b are not sealed by the light reflecting layer 103. Therefore, even when the light emitting element mounting substrate 100 is sealed with the glass lid 108, moisture may enter through the through holes 107a and 107b. More specifically, moisture may enter from the interface between the aluminum nitride substrate 102 and the through-hole electrodes 105a and 105b in the through-holes 107a and 107b. Therefore, in the light emitting element mounting package 101 of the comparative example, the airtightness is not sufficiently improved.

It is preferable that it contains. In particular, when sealing is performed by irradiating with a laser, the sealing glass has a low softening point in view of the necessity of softening the sealing material by heating for a shorter time and further enhancing the bonding strength. More preferably, powder is used. Further, the sealing material may contain a low expansion refractory filler, a laser absorber and the like.
