PURPOSE:To provide a confirming method of filling of molten resin and film in transfer molding, which can detect an arriving point of the molten resin easily, precisely and at a plurality of the points. CONSTITUTION:A pair of detecting patterns P, Q comprised of a conductive material are provided on confirming positions of filling of molten resin of a transfer film, end parts each of one side of the pair of detecting patterns P, Q are connected with each other by the conductive material 55 generating conductivity by heat and pressure of the molten resin at the time of injection molding, end parts each of the other side of the pair of the detecting patterns P, Q are connected with a signal detecting circuit through a taking-out contact point, the detecting patterns P, Q are made to communicate by the heat and pressure of the molten resin at the time of the molding and it is made so as to issue an ON signal. |
