To provide a stencil printing device wherein only a correct master roll and/or an ink container which are suitable for the device main body can be surely fitted, and at the same time, which can perform an electrical detection at a low cost.

This stencil printing device 100 is equipped with a plate-making means 71 and a master roll detecting means 24. In this case, the plate-making means 71 detachably supports this master roll 1, and at the same time, performs plate-forming for a master 1a which is pulled out from the master roll 1. Then, the master roll 1 has a coil L1 and a capacitor C1 inside, and has a resonant tag 3 for the master having a specified resonant frequency in the core section 2. The master roll detecting means 24 has a transmission control section 19 for the master, a transmitting antenna 8 for the master, a receiving control section 20 for the master, and a detecting antenna 9 for the master. In this case, the transmission control section 19 for the master transmits an electromagnetic wave of a specified frequency in order to identify the resonant tag 3 for the master. The receiving control section 20 for the master detects a reflective electromagnetic wave which is reflected from the resonant tag 3 for the master, when the frequency of the electromagnetic wave transmitted from the transmitting antenna 8 for the master reacts with the resonant frequency of the resonant tag 3 for the master. In such a stencil printing device 100, the transmitting antenna 8 for the master and the detecting antenna 9 for the master are arranged in the vicinity of the master roll 1.
