PROBLEM TO BE SOLVED: To provide a method for preparing a photosensitive composition which can allow a cured product having excellent thermal conductivity to be obtained without causing curing failure even when the photosensitive composition contains a heat radiating fine particle for absorbing/shielding irradiated light in high concentration.SOLUTION: The method for preparing the photosensitive composition containing a radical initiator (A), a polymerizable substance (D), the heat radiating fine particle (F) and an acid generator (B) and/or a base generator (C). The heat radiating fine particle (F) is a particle obtained by cubically expanding a mixture (X) of a thermal conductive material with a compressible fluid (L) to pulverize and/or crack the thermal conductive material.SELECTED DRAWING: None |
