PURPOSE: To make checking and additional wiring easier, when providing terminals for an element which sealed an electric circuit, by projecting the first terminal downwards towards a board on which a wiring pattern is made and projecting the second terminal which is connected inside upwards.

CONSTITUTION: When providing terminals for a sealing element 1 which contains an electric circuit, the first terminal 2 for packaging is projected downwards towards a packaging board 3 on which a wiring pattern 4 is prepared and connected to the pattern 4 using solder 5. The second terminal 6 which has been connected inside the element 1 is formed projecting above the upper surface of the element 1. By so doing, the element 1 can be checked easily with a probe 7 even after the element has been packaged to the board 3, and also additional wiring can be made easily. Also, the first terminal 2 may be projected from the side face of the element 1.
