Electronic apparatus, method of manufacturing substrate, and method of manufacturing electronic apparatus

1. An electronic apparatus comprising:

a substrate which has a step portion in an edge portion;

an electronic component which is bonded to a surface of the substrate inward of the step portion of the substrate;

a cap member which is bonded to the step portion and a wall surface so as to seal the electronic component; and

a metal layer disposed between the cap member and the substrate in a bonding region along the step portion and the wall surface,

wherein part of the metal layer is placed on top of the surface of the substrate to which the electronic component is bonded, and

wherein a wall surface of the step portion is formed to be inclined from the step portion toward an electronic component bonding region or to be perpendicular to the step portion.

2. The electronic apparatus according to claim 1 ,

wherein a connection portion of the wall surface and the step portion has an arc-shaped sectional shape.

3. The electronic apparatus according to claim 1 ,

wherein the shape of the surface inward of the step portion is substantially the same as the shape of an opening of the cap member in plan view.

4. The electronic apparatus according to claim 1 ,

wherein the cap member has a metal or a metal film in at least a contact portion with the substrate.

5. The electronic apparatus according to claim 1 ,

wherein the entire wall surface of the step portion is formed to be inclined from the step portion toward an electronic component bonding region.
