The present invention relates to a trisoxetane compound represented by the following formula (1):
wherein each of R
1
and R
3
's represents a hydrogen atom or an alkyl group having 1 to 6 carbon atom(s); R
2
represents a divalent aliphatic chained organic group having 0 to 16 carbon atom(s); and A represents a carbon atom or a trivalent organic group derived from a cycloalkane having 3 to 12 carbon atoms; a process for producing the same; and an optical waveguide including the same.
A curable resin composition includes (A) a specific curable resin and (C) a curing agent, and further includes (BI) 0.1 parts by mass or more and 20 parts by mass or less of a polyhydric alcohol having 2 to 5 hydroxyl groups, based on based on 100 parts by mass of the curable resin (A); (BII) a cyclic compound having 3 to 6 reactive groups and a reactive group equivalent of 100 g/eq or more and 300 g/eq or less; or (BIII) a specific oxetane compound in a mass ratio of the curable resin (A) to the oxetane compound (BIII) being 5:5 to 9:1.
