The present invention provides an acrylic ester compound represented by formula (1), a polymerizable composition containing the acrylic ester compound, and a cured product and an optical component obtained by polymerizing the polymerizable composition:
1
(wherein “a” is an integer of 0 to 4; R
1
is a directly bonded single bond, an alkylene group, an aralkylene group or arylene group which may have a substituent, or a —Y
3
—S—R
4
—S—Y
4
— group (R
4
is an alkylene group, an aralkylene group or an arylene group; and Y
3
and Y
4
are each an alkylene group); R
2
and R
3
are each a hydrogen atom or an alkyl group; X
1
and X
2
are each an oxygen atom or a sulfur atom; and Y
1
and Y
2
are each an alkylene group which may contain an oxygen atom or a sulfur atom).
