Abstract
A circuit board includes a core layer, a first via structure penetrating the core layer, a circuit wiring disposed on one surface of the core layer and including a head portion in contact with the first via structure, a connection portion extending from the head portion and an extension portion electrically connected to the head portion through the connection portion, and a first ground pattern disposed on the one surface of the core layer and disposed around the circuit wiring to be spaced apart from the circuit wiring. A shortest distance between the extension portion and the first ground pattern is greater than a shortest distance between the head portion and the first ground pattern.
