  • Publication number: 20140251659
    Abstract: A circuit board, onto which an electronic component is to be mounted, is provided with insulating core substrates and patterned metal plates. The metal plates are bonded to at least one side of the insulating core substrates. The insulating core substrates and the metal plates form a laminated body, in which a gas-vent hole is provided. The gas-vent hole is formed so that when the electronic component is mounted, the gas present between the insulating core substrates and the metal plates expands and is released to a side open to the atmosphere via the gas-vent hole.
