    • A protection element and a secondary battery device employing the protection element are provided for stably retaining a flux on a soluble conductor at a predetermined position, so as to enable appropriate blowout of the soluble conductor in the event of an abnormality. The protection element has a soluble conductor which is disposed on an insulation baseboard, and which is connected to a power supply path of a device targeted to be protected, and which causes a blowout when a predetermined abnormal electric power amount is supplied. A flux is coated on a surface of the soluble conductor, and an insulation cover member is mounted on the baseboard and covers the soluble conductor. The protection element also includes a stepped portion for retaining the flux at a predetermined position in contact with the flux, and the stepped portion is formed opposite to the soluble conductor on an interior face of the insulation cover member.
    • 提供一种使用保护元件的保护元件和二次电池装置,用于将预定位置上的可溶性导体上的助熔剂稳定地保持,从而能够在发生异常时适当地喷出可溶性导体。 保护元件具有设置在绝缘基板上的可溶性导体,其与被保护对象的装置的电源路径连接,当提供规定的异常电力量时,产生喷出。 助焊剂涂覆在可溶性导体的表面上,绝缘覆盖件安装在基板上并覆盖可溶性导体。 保护元件还包括用于将焊剂保持在与焊剂接触的预定位置的阶梯部分,并且阶梯部分形成在绝缘覆盖部件的内表面上与可溶性导体相对。
