A suspension coil spring device may include a compression coil spring (10) that has a coating film, a rubber vibration isolator, and an adhesive layer that joins the compression coil spring and the rubber vibration isolator 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.
