Case and timepiece

A case comprising:

• a first member having a first surface;
• and
• a second member having a second surface and a third surface inclined at a prescribed angle to the second surface, the second surface being arranged to align with the first surface of the first member,
• wherein a welding portion of the first surface of the first member and a welding portion of the second surface of the second member form a welded surface, and
• wherein the second member has a regulating part which regulates spreading of melted material on the third surface, and a part of the regulating part is formed by the second surface.

A case comprising:

• a first member;
• and
• a second member,
• wherein the second member has a recess part on a surface that intersects with a welding surface where a welding part of the first member and the second member is located,
• wherein laser light is irradiated onto the welding part of the first member and the second member, and
• wherein the recess part is located at a position where reflected light reflected on the welding surface is irradiated.

A case comprising:

• a first member;
• and
• a second member,
• wherein the second member has a recess part on a surface that intersects with a welding surface where a welding part of the first member and the second member is located, and
• wherein a contact surface of the first member and the second member includes a first abutting surface parallel with a thickness direction of the first member and a second abutting surface perpendicular to the thickness direction of the first member.

A case comprising:

• a first member;
• and
• a second member,
• wherein the second member has a recess part on a surface that intersects with a welding surface where a welding part of the first member and the second member is located, and
• wherein a contact surface of the first member and the second member includes a first abutting surface parallel with a thickness direction of the first member and a second abutting surface perpendicular to the thickness direction of the first member.
