1. A combustor component of a combustor for combusting fuel to produce a combustion gas, comprising:
a combustion cylinder forming a passage for the combustion gas;
a first acoustic device which internally includes a first cavity communicating with the passage via a first through hole formed in the combustion cylinder;
a second acoustic device which is located on a radially outer side of the first acoustic device so as to cover the first acoustic device, and internally includes a second cavity communicating with the passage via a second through hole formed in the combustion cylinder;
a first communication passage causing the first cavity and an outer space, which is a space outside of the combustion cylinder and the combustor component, to communicate with each other without via the first through hole and the second cavity; and
a partition wall separating the second cavity from a partition space on a radially inner side of the second cavity,
wherein the first communication passage causes the first cavity and the outer space of the combustion cylinder to communicate with each other via the partition space.
