A suspension coil spring device (1) includes a compression coil spring (10) that has a coating film, a rubber vibration isolator (20), and an adhesive layer that joins the compression coil spring (10) and the rubber vibration isolator (20) to each other. The adhesive layer is a cured product of a hot melt adhesive that melts at 80°C to 100°C. A softening point of the hot melt adhesive is lower than a heat-resistant temperature of the coating film. The softening point of the hot melt adhesive is lower than a heat-resistant temperature of the rubber vibration isolator (20).
