Abstract
An adhesive composition including a polymerizable monomer having a (meth)acryloyl group; a radical polymerization initiator; and a polymer particle having a property of being swollen by an organic solvent, in which in a particle size distribution of secondary particles which are aggregates of the polymer particles, the secondary particles being in the adhesive composition and the particle size distribution being determined by a laser diffraction/scattering method, a proportion of secondary particles having a diameter of 1 μm or more and 200 μm or less is 30% by volume or more.
