Buffer member, shock buffering structure of electronic device, and electronic device

An electronic device comprising:

• a device case;
• a module which is housed inside the device case and has electronic components mounted therein;
• and
• a buffer member which is interposed between the device case and the module, and absorbs shock;
• wherein the buffer member is composed of a viscoelastic body which, when the device case receives shock, reduces the shock to be transmitted to the module by changing shape in proportion to a magnitude of the shock while converting kinetic energy to heat energy, and quickly reduces elastic force on the module by reducing conversion of the kinetic energy to elastic energy accompanying the shape change;
• and
• the viscoelastic body is composed of a first viscoelastic body section, a second viscoelastic body section, and a third viscoelastic body section, of which the first viscoelastic body section is formed into a cylindrical shape to cover a top surface and a side surface of the module, the second viscoelastic body section is arranged in predetermined portions of the first viscoelastic body section with space therebetween, and the third viscoelastic body section is arranged in a frame shape along an inner peripheral edge of a top surface of the first viscoelastic body section positioned on the top surface of the module.
