PROBLEM TO BE SOLVED: To provide a spark plug connector capable of being manufactured at a low cost and capable of being inserted for secure electrical connection. SOLUTION: This spark plug connector is provided with an insulating casing 2, and a contact element 5 to be electrically connected to a terminal part 19 of the spark plug 20 is arranged in a spark plug housing part 6, and the contact element 5 can be pushed by the terminal part 19 of the spark plug 20, while resisting the elastic force for returning work. The casing 2 is made of an elastic material, and a curved spring as the contact element 5 is embedded in the casing material. The block of curved leg parts (10), 11 of the curved spring 5, in which contact is possible, is formed with the minimum diameter part of the spark plug housing part 6 within a contact flat surface 14 which is vertical with respect to a vertical axis line 16 of the spark plug housing part 6.
