PROBLEM TO BE SOLVED: To provide a heat-insulating type underfloor storage which facilitates the attachment of a solid heat-insulating material, has high heat-insulating performance, and makes a lid for preventing the heat-insulating material from falling freely attachable/detachable. SOLUTION: In this heat-insulating type underfloor storage, the lid 5 for opening/closing wherein a cover body 4 including the box-shaped heat-insulating material is fixedly attached to a backside 3 of a lid body 2 can be freely attached to/detached to/from a storage box 1. The heat-insulating type underfloor storage is formed in such a manner that the solid heat-insulating material 7 and a fibrous heat-insulating material 8 are laminated on the bottom 6 of the cover body 4 so as to be fixedly attached to the backside 3 of the lid body 2. The material 7, which is composed of a foamed resin board of a foamed urethane resin, a foamed phenol resin, etc., is fixedly attached to the bottom 6 of the cover body 4 of the lid 5; and the material 8 wherein a binder (binding material) such as a resin is mixed into rock wool, glass wool, etc. is sprayed to the material 7, and intrudes into a gap at the corner 9 of the bottom 6 of the cover body 4 so as to be fixedly attached in a state of completely eliminating the gap.
