A method of adhesion comprising: (i) a step 1 of heating a curable resin composition to a first temperature and applying the curable resin composition to a first adherend so as to have a first thickness; (ii) a step 2 of spreading, to a second thickness, the curable resin composition that has been applied, the spreading being performed in an environment at a second temperature, the spreading being performed prior to or simultaneously with affixing a second adherend to the first adherend; and (iii) a step 3 of curing the curable resin composition sandwiched between the two adherends that have been affixed to each other, the first temperature being higher than the second temperature, and the second thickness being less than the first thickness, the curable resin composition containing: an epoxy resin; fine polymer particles that have a core-shell structure including a core layer and a shell layer, the shell layer having a cyano group, a volume-average particle size (Mv) of the fine polymer particles being 10 nm to 2000 nm, as determined by the method defined in the description; and blocked urethane, the fine polymer particles being contained in an amount of 1 part by mass to 100 parts by mass with respect to 100 parts by mass of the epoxy resin, the blocked urethane being contained in an amount of 1 part by mass to 100 parts by mass with respect to 100 parts by mass of the epoxy resin, a ratio (W1/W2) of a mass of the fine polymer particles to a mass of the blocked urethane being 0.1 to 10.0; a contained amount of the cyano group with respect to the total mass of the shell layer of the fine polymer particles being 5.0 mmol/g to 10.0 mmol/g.
