Abstract: A terminal fitting (10) includes a terminal main body (11) and a shell (12), which is a component separate from the terminal main body (11). The terminal main body (11) has a fitting portion (18) and resilient contact pieces (14). The shell (12) is a rectangular tube engaged with the fitting portion (18) of the terminal main body (11) and surrounding the resilient contact pieces (14). Even though being relatively expensive, an electrically conductive material such as copper alloy needs to be used as the material of the terminal main body (11) formed with the resilient contact pieces (14). However, an inexpensive material can be used for the shell (12) since electrical conductivity is not required. Therefore, cost can be reduced as compared with the case where a terminal fitting is made entirely of an expensive electrically conductive material.
