An ink composition containing a P-type semiconductor material, an N-type semiconductor material and two or more solvents including a first solvent and a second solvent, wherein
the total amount of the first solvent and the second solvent is 70% by weight or more with respect to 100% by weight of all the solvents contained in the ink composition;
the boiling point of the first solvent is lower than the boiling point of the second solvent;
the boiling point of the first solvent is 120° C. or more and 400° C. or less; and
the hydrogen bond Hansen solubility parameter H1 (MPa
0.5
) of the first solvent and the hydrogen bond Hansen solubility parameter H2 (MPa
0.5
) of the second solvent are in the relation of 0.5≦(H2−H1)≦5.0.
