Container box and substrate set

A container box comprising:

• a first substrate which is mounted to a second substrate having a standing wall, the standing wall having a bottom edge being parallel to the second substrate and being in an opposite side of a surface of the second substrate to which the first substrate is mounted;
• a bottom surface;
• a plurality of side surfaces that include a first side surface and a second side surface;
• a top surface;
• a first edge along which the bottom surface and the first side surface contact;
• a second edge along which the bottom surface and the second side surface contact;
• and
• a third edge along which the first side surface and the second side surface contact,
• wherein if the top surface is opened, the first side surface and the second side surface are capable of being separated at the third edge,
• wherein a length of the third edge is substantially equal to a shortest length between the bottom edge of the standing wall and a contact line between the second substrate and the standing wall,
• wherein a length of the first edge is longer than a length of an edge of the first substrate and a half length of an edge of the second substrate, and
• wherein a length of the second edge is longer than a length of another edge of the first substrate and a half length of another edge of the second substrate.

A substrate set comprising:

• a first substrate;
• a second substrate to which the first substrate is mounted, the second substrate having a standing wall, the standing wall having a bottom edge being parallel to the second substrate and being in an opposite side of a surface of the second substrate to which the first substrate is mounted;
• and
• a container box that contains the first substrate, the container box including
• a bottom surface,
• a plurality of side surfaces that include a first side surface and a second side surface,
• a top surface,
• a first edge along which the bottom surface and the first side surface contact,
• a second edge along which the bottom surface and the second side surface contact, and
• a third edge along which the first side surface and the second side surface contact,
• wherein if the top surface is opened, the first side surface and the second side surface are capable of being separated at the third edge,
• wherein a length of the third edge is substantially equal to a shortest length between the bottom edge of the standing wall and a contact line between the second substrate and the standing wall,
• wherein a length of the first edge is longer than a length of an edge of the first substrate and a half length of an edge of the second substrate, and
• wherein a length of the second edge is longer than a length of another edge of the first substrate and a half length of another edge of the second substrate.
