    Abstract: Provided is a protecting device that can prevent damage of the device by releasing the pressure inside the housing by providing openings in the housing and can secure appropriate insulation. The protecting device includes: a meltable conductor 3; first and second external connection terminals 7, 8 connected to both ends of the meltable conductor 3; and a housing 6 having a lower case 4 and an upper case 5, wherein one end of the first external connection terminal 7 and one end of the second external connection terminal 8 are led out from the housing 6, and the housing is provided with a first opening 24 formed facing a front surface of the first external connection terminal 7 and a second opening 25 formed facing a front surface of the second external connection terminal 8.

    Abstract: Provided are a protecting device capable of safely and quickly interrupting a current path by restricting heat absorption to a lower case, and a battery pack using the same. A protecting device includes: a meltable conductor 3; and a housing 6 including a lower case 4 and an upper case 5, the housing being formed by joining the lower case 4 and the upper case 5, and the lower case 4 is provided with a recessed portion 23 having support portions 21 provided at opposing side edges of the recessed portion 23 and hollow portions 22 provided on the side edges substantially orthogonal to the side edges of the recessed portion 23 on which the support portions 21 are provided.

    Abstract: A fuse element capable of surface-mounting and capable of increased ratings while maintaining high-speed blowout property; and a fuse device using the same. A fuse element blown by self-generated heat caused when a rate-exceeding current flows therethrough constitutes a current path of a fuse device and has a low melting point metal layer and a high melting point metal layer laminated onto the low melting point metal layer; when the current flows therethrough, the low melting point metal layer erodes the high melting point metal layer and blowout occurs.
