Vibration damping device

A vibration damping device, comprising:

• a vulcanized rubber molding having a vibration isolating function,
• a resin molding integrally formed with the vulcanized rubber molding fixed to a base body while supporting the vulcanized rubber molding,
• wherein the resin molding includes a sandwiched molding having a core layer and skin layers sandwiching the core layer,
• a first resin composition (A) included in the skin layers, which includes a first thermoplastic resin and an inorganic filler,
• a second resin composition (B) included in the core layer, which includes a second thermoplastic resin and an inorganic filler, wherein
• a volume ratio of the skin layers is in a range of 40% to 70% of the entire sandwiched molding, and wherein
• a bending modulus (E1) of the skin layers, a maximum bending strain (ε1) of the skin layers, a bending modulus (E2) of the core layer, and a maximum bending strain (ε2) of the core layer satisfy the following expressions (1) and (2):
• 1<(E1/ε1)<(E2/ε2)<10 (1)
• ε1/ε2>1 (2).
