PROBLEM TO BE SOLVED: To provide a key switch device that can assemble a link member and a holder member easily and can realize good key operation while maintaining a large key stroke without obstructing a descent motion of a key top halfway. SOLUTION: A thick will part 21a is formed integrally on the inside of a linking portion of a pair of plate-like body 17 and a lock bar 21 in a second link member 8 so as to project both end parts of the lock bar in pin form. On the inside part of a lock bar 13 formed between ends of a pair of plate-like body 9 in a first link member 7, a thick part 13a in plan view is formed integrally. Furthermore, both ends of the first link member 7 and the second link member 8 are formed thin as compared with the center in side view.
