An ESD protective triggering circuit for a triggering circuit for a solid state ESD protective device. Notifications, representing an occurrence of an event, are received at a notification manager from applications. The electrodes are receptive to a power source. From the warm side, the compressed hydrogen and, from the cold side, liquefied hydrogen can be supplied from the storage tank for liquefied hydrogen. The thin film transistor is provided between a first structural body and a second structural body, which has a higher rigidity than the first structural body, which serve as protectors because the structural bodies have resistance to a pressing force such as a tip of a pen or bending stress applied from outside so malfunction due to the pressing force and the bending stress can be prevented. Accordingly, a shaft can be securely inserted into the second insertion hole and the positioning hole so as to be fastened with the head shell.
