A B-share (Swedish: B-aktie) is a share class that usually has lower voting power than the company's A-shares. A common arrangement is that a B-share carries one vote and an A-share ten votes. Unless the articles of association state otherwise, the B-share otherwise has the same right to the company's profits and assets.
B-shares are common in listed companies, but also occur in unlisted companies. The share ledger must show which share class each share belongs to, so the distribution of votes can be followed.

Share class refers to different types of shares in a company, e.g. A and B shares, with different rights.
