A PCB(Print Circuit Board) having a multi pathway is provided to improve contact efficiency by dispersing air between a movable contact and a fixing contact. A PCB(100) having a multi pathway includes a base frame(10), a conductive layer(20), movable contacts(40), and a dispersion pathway(22). The conductive layer is positioned on an upper part of the base frame and includes fixing contacts(21) and circuit patterns. The movable contacts are installed on upper parts of the fixing contacts and contact the fixing contacts. The dispersion pathway is formed by etching the conductive layer and disperses air between the conductive layer and the movable contacts by pressing the movable contacts.
