Abstract: A press-fit fixing terminal is mountable to a wiring board by being inserted into a through-hole of the wiring board, and includes a flat plate section and a resilient contacting section. The flat plate section is made of metal thin plate and double-backed such that an end of the flat plate section is placed on a root side and a bent point works as an insertion tip when the terminal is inserted into the through-hole. The resilient contacting sections sandwich the double-backed portion of the flat plate section such that they are placed symmetrically with respect to the double-backed portion and both of the ridges of the resilient contacting section face outward viewed from the double-backed portion, so that each one of the resilient contacting sections forms a V-shape including an obtuse angle.
