Casing, electronic device, and mobile body

An electronic device comprising:

• a substrate;
• and
• a casing that is made of metal and houses the substrate, wherein
• the casing includes a first component and a second component that are arranged in a thickness direction of the substrate,
• the first component includes:
• a first face portion that is rectangular and covers a first principal face of the substrate;
• a first standing portion that stands from one edge of the first face portion in a crosswise direction of the first face portion;
• and
• a second standing portion that stands from an other edge of the first face portion in the crosswise direction, the second component includes:
• a second face portion that is rectangular and covers a second principal face disposed on a reverse side of the first principal face;
• a first contact portion that stands from one edge of the second face portion in the crosswise direction and overlaps an outer face of the first standing portion with contact therebetween;
• and
• a first overlap portion that stands from an other edge of the second face portion in the crosswise direction and overlaps an outer face of the second standing portion with a gap therebetween, and
• at least one of the second standing portion or the first overlap portion includes a first protruding portion that maintains the gap between the second standing portion and the first overlap portion at a predetermined distance and generates pressure between the first standing portion and the first contact portion.

A mobile body comprising:

• an electronic device including a substrate and a casing that is made of metal and houses the substrate, wherein

• a second face portion that is rectangular and covers a second principal face disposed on a reverse side of the first principal face;
• a first contact portion that stands from one edge of the second face portion in the crosswise direction and overlaps an outer face of the first standing portion with contact therebetween;
• and a first overlap portion that stands from an other edge of the second face portion in the crosswise direction and overlaps an outer face of the second standing portion with a gap therebetween, and
• at least one of the second standing portion or the first overlap portion includes a first protruding portion that maintains the gap between the second standing portion and the first overlap portion at a predetermined distance and generates pressure between the first standing portion and the first contact portion.
