Bonding method and bonded body

A bonding method of forming a bonded body in which a first base member and a second base member are bonded together through a bonding film having a predetermined pattern, the bonding method comprising:

• applying a liquid material containing a silicone material composed of silicone compounds onto a surface of at least one of the first and second base members using a liquid droplet ejecting method, to form a liquid coating having a pattern corresponding to the predetermined pattern on the surface;
• drying the liquid coating so that it is transformed into the bonding film having the predetermined pattern on the surface of the at least one of the first and second base members;
• first applying energy to the bonding film so that a bonding property is developed in the vicinity of a surface thereof, wherein the first applying energy includes irradiating an ultraviolet ray on the bonding film, heating the bonding film, and applying a compressive force to the bonding film;
• making the first and second base members contact with each other through the bonding film to obtain the bonded body;
• and
• second applying energy to the obtained bonded body,
• wherein the second applying energy includes irradiating an ultraviolet ray on the obtained bonded body, heating the obtained bonded body, and applying a compressive force to the obtained bonded body, and
• wherein a surface of each of the first and second base members which makes contact with the bonding film has been, in advance, subjected to a surface treatment for improving bonding strength between each of the first and second base members and the bonding film, and wherein the surface treatment is an ultraviolet ray irradiation treatment.
