A press-fit terminal includes a pair of the resilient contacts being swelled outward, and having a deformation space into which the resilient contacts are deformed. The press-fit terminal is electrically connected to a conductive inner wall of a through-hole on a circuit board by pressing the press-fit terminal into the through-hole. The press-fit terminal includes abutting portions on each inner wall of the pair of the resilient contacts. When the abutting portions abut on each other, the abutting portions regulate deformation of the resilient contacts in a narrowing direction to narrow the deformation space. Then inclined walls formed on the abutting portions induce the resilient contacts to slide on the inclined walls in a direction to separate the resilient contacts from each other.
