Photosensitive composition

A photosensitive composition comprising a radically polymerizable compound (A) and a radical polymerization initiator (C), wherein the radically polymerizable compound (A) comprises a compound (A1) represented by following formula (A1):

• wherein, in the formula (A1), Xa is —S—, —O—, or —NH,
• Ara01 is an aromatic hydrocarbon group having a valence of (ma2+1) or an aromatic heterocyclic group having a valence of (ma2+1),
• Ra01 and Ra02 are each independently an aromatic hydrocarbon group, an aromatic heterocyclic group, or a group represented by following formula (A1a):
• Ra03—(Xa03—Xa02)ma4—(Xa01)ma3— (A1a)
• among ma1 Ra0 and ma2 Ra02(s), at least one is the group represented by the formula (A1a),
• ma1 is 0 or 1,
• ma2 is 0, 1, or 2,
• when ma2 is 2, two Ra2s may be the same or different,
• at least one of ma1 and ma2 is not 0,
• Xa01 is oxygen atom,
• Xa02 is an alkylene group which may be interrupted by one or more oxygen atoms,
• Xa03 is oxygen atom,
• Ra03 is a radically polymerizable group-containing group,
• ma3 and ma4 are each independently 0 or 1, and
• in the compound represented by the formula (A1), sum of numbers of oxygen atoms derived from Xa01, Xa02, and Xa03 included in the group represented by the formula (A1a) is 1 or more, and
• other radically polymerizable compound (A2) than the compound (A1).
