1. An electric cable with terminal in which an end of an electric cable is connected to a terminal,
the electric cable comprising a core wire that is a bundle of a plurality of wire strands, and
the terminal comprising a connection portion that is connected to the core wire that is exposed at the end of the electric cable,
wherein the core wire comprises a segment of the bundle of the plurality of the wire strands that is spaced apart from the terminal, and a welded portion in which the core wire placed on the connection portion is ultrasonically welded to the connection portion, the welded portion being located at a position closer to an end of the core wire than the segment is,
the welded portion comprises a high compression portion where the core wire is compressed, and a low compression portion where the core is compressed at a compression that is lower than that of the high compression portion, the low compression portion being located at a position that is closer to the end of the core wire than the high compression portion is, and
the segment is provided with an inclined portion in which an outer circumferential surface of the bundle of the plurality of the wire strands is continuously and obliquely inclined with respect to a longitudinal direction of the terminal, and the inclined portion is compressed.
