PROBLEM TO BE SOLVED: To provide a dome switch which can absorb slack grown up at a circuit object. SOLUTION: The dome switch is equipped with a front sheet 22 with dome- shaped projected section 27 which projects toward outside and can also be projected reversely toward inside where an electrode 28 is arranged, an FPC 24 as a circuit object with a contact 35 to get in touch with the electrode 28 arranged at a projected section of the front sheet when it is reversely projected toward inside, and a spacer sheet 23 interposed between the front sheet 22 and the FPC 24 forming a through-hole 29 securing contact between the electrode 28 and the contact 35. A slack-absorbing space section 31 is formed in the spacer sheet 23 to absorb slack 42 grown up at the FPC 24 when bent.
