算機能付き電子式腕時計を提供するものてある。However, this interconnector is inserted between the electrode board and the circuit board and is held and installed by pressing from both board sides, but since the interconnector is not directly fixed to the circuit board, the installation strength is limited. This structure is weak, and when applied to a wristwatch, etc., there is a risk that it may become misaligned or come off due to external impact force, resulting in an incomplete electrical connection between the two boards. . The present invention has been made in view of the above circumstances, and provides an electronic wristwatch with a calculation function that electrically connects a circuit board and a keyboard electrode board on which electrodes are formed using an interconnector.
To provide an electronic wristwatch with a calculation function that not only has a simple structure and can reliably attach an interconnector, but also has improved impact resistance of the interconnector.

Therefore, the electrode substrate 8 and the circuit board 11 are provided on the upper and lower sides of the upper part 2a of the housing 2 and are arranged in a layered structure. Further, in the upper part 2a of the housing 2, a pair of elongated through holes 13, 13 for inserting interconnectors 14, 14 are formed side by side. The interconnectors 14, 14 are elongated rod-shaped, and a conductive member 14a is provided on the circumferential surface of each of the interconnectors 14, 14. The interconnectors 14, 14 are inserted into the through holes 13, 13 so as to closely match with each other, their upper and lower surfaces abut against the electrode board 8 and the circuit board 11, and the conductive members 14a... The conductive terminal 10b of the board 8 and the circuit 12 of the circuit board 11 are electrically connected. In this case, interconnector 1

る。Therefore, since the keyboard electrode board and the circuit board have a two-layer structure, the wristwatch can be made smaller even if it is equipped with a calculation keyboard, and the switch electrodes of the keys are guided to the bottom surface of the keyboard electrode board. Since the keyboard is placed opposite the circuit on the circuit board, electrical connection can be made simply by using a long, thin rod-shaped interconnector, making electrical connection between the keyboard and the electronic circuit extremely simple. . Since the interconnector is placed in the through hole of the insulating frame that holds the circuit board, the interconnector will not be deformed or damaged, and will not move even if the wristwatch is subjected to impact. Electrical connection between the keyboard section and the electronic circuit via the interconnector is maintained.
