1. A circuit board, comprising:
a board body;
a card slot disposed on the board body and adapted for inserting an expansion card;
a release structure pivotably disposed beside the card slot, the release structure including a pivotal shaft such that the release structure is pivotable about the pivotal shaft; and
a transmission mechanism disposed on the board body, extending along a surface of the board body, and comprising a contact part, a stressed part, and a linkage part that is connected to the contact part and is in contact with the stressed part, wherein the contact part is connected to the release structure, the pivotal shaft being located between the card slot and the contact part,
wherein when the stressed part receives an external force, the contact part is moved via the linkage part correspondingly, so that the release structure is pivoted relative to the card slot about the pivotal shaft, thereby releasing the expansion card.
