Semiconductor device

A semiconductor device, comprising:

• a first semiconductor chip and a second semiconductor chip;
• and
• a wiring unit including
• a first wiring member having a first one end portion electrically connected to the first semiconductor chip,
• a second wiring member having a second one end portion electrically connected to the second semiconductor chip, and
• a wiring holding portion holding a part of the first wiring member and a part of the second wiring member, wherein:
• the first wiring member includes
• a first horizontal portion parallel to a principal surface of the first semiconductor chip,
• a first vertical portion perpendicular to the first horizontal portion, and
• a first bent portion bent to connect the first horizontal portion and the first vertical portion;
• the second wiring member includes
• a second horizontal portion, a surface of which is flush with a surface of the first horizontal portion,
• a second vertical portion disposed at a determined distance from the first vertical portion to form a first gap, and having a surface parallel to a surface of the first vertical portion, and
• a second bent portion bent in a direction opposite to the first bent portion to connect the second horizontal portion and the second vertical portion, the second bent portion disposed at a determined distance from the first bent portion to form a second gap;
• and
• the wiring holding portion is configured to fill the first gap between the first vertical portion and the second vertical portion and the second gap between the first bent portion and the second bent portion.
