PROBLEM TO BE SOLVED: To provide a switch device and an electronic stethoscope which can be made compact easily while reducing the manufacturing cost.SOLUTION: A switch device includes a plurality of switches mounted on a substrate, an operation part where a plurality of protrusions approaching the plurality of switches, respectively, or separating therefrom are provided to face the switches separately therefrom, and a support 23 located between the substrate and the switches while being held on the substrate, and supporting the operation part elastically so that it can tilt in a plurality of directions. The plurality of protrusions in the operation part, which are pressed against resiliency of the support 23 or released, turn the plurality of switches on/off selectively. The support 23 has a held portion 232 held on the substrate and having an opening facing the operation part, a support portion 231 located in the opening in the held portion 232 separately from the rim of the opening, and supporting the operation part tiltably, and a spiral or open circular resilient portion 233 coupling the held portion 232 and support portion 231 at both ends, and deforming in accordance with tilting of the operation part and support portion 231.COPYRIGHT: (C)2014,JPO&INPIT【課題】小型化が容易であり、製造コストを抑えることができるスイッチ装置及び電子聴診器を提供する。【解決手段】基板上に実装された複数のスイッチと、複数のスイッチ夫々に対して接近又は離反する複数の突起が複数のスイッチから隔離対設された操作部と、基板及び操作部の間に位置して基板に保持され、操作部を複数方向に傾動可能にかつ弾性的に支持する支持体23とを備え、支持体23の弾性に抗して押圧又は押圧解除された操作部における複数の突起が複数のスイッチを選択的にオン/オフするスイッチ装置において、支持体23は、基板に保持され、操作部に対向する開口が設けられた被保持部232と、被保持部232の開口内にて開口の周縁から離隔配置され、操作部を傾動可能に支持する支持部231と、被保持部232及び支持部231を両端部で連結し、操作部及び支持部231の傾動に応じて変形する渦巻状又は開環状の弾性部233とを有する。【選択図】図6
