Claim:
1. A fuse comprising: a fuse element which includes a first planar terminal part, a second planar terminal part, a fusible conductor part, a melting part, and a low melting point metal chip, wherein the melting part is connected to the fusible conductor part at a location that is between parallel inner side edges of the first planar terminal part and the second planar terminal part, and the fuse element further includes a front surface side that extends along each of the first planar terminal part, the second planar terminal part, and the fusible conductor part; and an insulative housing, having a melting part accommodating space to accommodate the melting part therein, which is mounted to the front surface side of the fuse element to cover the inner side edges of the first planar terminal part and the second planar terminal part and the melting part, wherein the low melting point metal chip is mounted on a portion of the front surface side that extends along the fusible conductor part, the low melting point metal chip extends from the front surface side and into the melting part accommodating space, and the front surface side where the low melting point metal chip is mounted to the fusible conductor part is located outside of the melting part accommodating space, and welding bosses, which are protruded from a mounting surface of the insulative housing located outside of the melting part accommodating space, are welded in engaging recesses which are formed at the upper and lower edges of the first planar terminal part and the second planar terminal part.
