Adhesive composition, covering substrate, and cured product

An adhesive composition comprising:

• a cyclic organosilazane compound of the following general formula (1):
• wherein R1s each independently represent a substituted or unsubstituted monovalent hydrocarbon group having 1 to 10 carbon atoms, and p represents an integer of 3 to 8;
• and
• a hydrolyzable group-containing organosilicon compound containing an alkoxysilane compound of the following general formula (2) and/or a partial hydrolytic condensate thereof:
• R2x—Si(OR3)4-x (2)
• wherein R2 represents an unsubstituted monovalent hydrocarbon group having 1 to 10 carbon atoms or an alkyloxyalkyl group, R3 represents an unsubstituted monovalent hydrocarbon group having 1 to 10 carbon atoms, and x represents an integer of 0 to 2, and
• a solvent, wherein the solvent is an isoparaffin compound or a silicone compound having 2 to 8 silicon atoms.
