A member bonding structure having both high bonding reliability and high repairability is provided. A member joining structure of the present invention includes a first connection target member (2), a second connection target member (1), a first connection target member (2), and a second connection target member (1). And an adhesive layer (3) having a thermoplastic resin and a thermosetting resin in a state of being compatible with each other, wherein the adhesive layer (3) is a thermoplastic resin rich mainly containing a thermoplastic resin. It has a layer (30) and a thermosetting resin-rich layer (31) mainly containing a thermosetting resin. According to the absolute value of the difference between the solubility parameter of the thermoplastic resin and the solubility parameter of the thermosetting resin, the content of the thermoplastic resin in the entire resin including the thermoplastic resin and the thermosetting resin is set to a predetermined range. It is something. [Selection diagram] Fig. 1 |
