Electronic device and electronic apparatus

An electronic apparatus comprising:

• a functional element;
• and
• a package adapted to house the functional element,
• wherein the package includes:
• a base substrate adapted to fix the functional element and provided with a light passage hole through which light passes,
• an external terminal formed on a surface of the base substrate that is opposite to the functional element, and
• a light transmissive substrate adapted to block the light passage hole and provided with a light transmissive property,
• the base substrate is formed of a laminated body having a plurality of layers stacked on each other, and
• the light passage hole is formed so that a second opening located on an opposite side to the functional element is larger in area than a first opening located on the functional element side, and the light passage hole includes:
• a first light passage hole,
• a second passage hole located nearer to the second opening than the first light passage hole, and larger than the first light passage hole, and
• a step section provided to a connection section between the first light passage hole and the second light passage hole,
• wherein the light transmissive substrate is fixed to the base substrate via a bonding material provided to the step section,
• the step section has a tip portion curved toward the second opening, and
• a thickness of the bonding material gradually decreases toward the tip portion of the step section.
