PROBLEM TO BE SOLVED: To provide a method for satisfying different demands from the customers to the key structure in situation, such as in the conventional key operations, where multiple numbers of operation keys with different functions are positioned adjacent in consideration of designing and functioning, while these operation keys are desirably formed as units using resin if the cost of manufacturing is critical, so as to solve the problem in that the demand from the customers are diversified, e.g. the demand for each operation key to be made with different colors. SOLUTION: The key structure is composed of constituents, such as a frame 36, multiple supports 38 downing from the frame 36, multiple key tops 31 or the like connected jointly to the inside of the frame 36 via the support arms 35, 37 and the pillar-like pressing material 39 or the like extending from the lower side of each key tops. At least one key top is composed of the base portion 33 connected jointly to the support arm and the key top body 52 mounted with respect to the base 33 with possible detachment. The key top body 52 and all the structural components except for the key top body 52 are molded integrally, respectively.
