The present disclosure provides a conductive agent and a module bonding method. In the method, a conductive agent is sprayed to a bonding region. The conductive agent comprising a liquid ultraviolet curable adhesive and conductive particles dispersed in the ultraviolet curable adhesive. A module layer is pre-pressed onto the bonding region with the conductive agent between the module layer and the bonding region. The conductive agent is cured by irradiating the conductive agent with ultraviolet rays and pressurizing the conductive agent, so that the module layer is electrically connected and bonded to the bonding region.
