To easily perform replacement of a fixing member for fixing an object on a skin of a human body.An electronic device includes a biological signal acquisition device, a first sheet, and a second sheet. The biological signal acquisition device acquires a biological signal of the human body in a state of being fixed to the skin of the human body. The first sheet has one surface to be bonded to the biological signal acquisition device and another surface to be bonded to another sheet. Furthermore, a bonding strength per unit area between the other surface of the first sheet and the other sheet is larger than a bonding strength per unit area between the one surface of the first sheet and the biological signal acquisition device. The second sheet includes one surface to be bonded to the other surface of the first sheet and another surface to be bonded to the skin of the human body. Furthermore, the bonding strength per unit area between the one surface of the first sheet and the biological signal acquisition device is larger than a bonding strength per unit area between the other surface of the second sheet and the skin of the human body.
