PURPOSE:To make the shape of contacts of a terminal board of an electronic component such as a piezoelectric resonator uniform and to attain ease of manufacture of the terminal board by providing a slot through which the component is inserted from a flat face in contact with the electronic component at the tip of a contact toward the terminal board main body. CONSTITUTION:A punch hole with a small diameter is made on the center of the terminal board 15 by a press to swell the peripheral part of the hole thereby forming a taper contact part 16 projected from the main body of the terminal board 15 in the normal direction. A face is formed by a press to the tip of projected part 16 to form a flat face 19 in press contact with an electrode 1. Then three V slots 20 are formed on the flat face 19 toward the main body side of the terminal board 15. The contact area between the contact 16 and the electrode 1 is set optionally by adjusting the number and the length in circumferential direction of the V slots 20 and a desired electric characteristic is provided to a piezoelectric resonator 3. |
