1. A cooling channel structure, comprising:
a first wall section extending along a first direction;
a second wall section disposed at an interval from the first wall section in a second direction orthogonal to the first direction;
at least one cooling channel which has a plurality of channel cross-sections disposed at intervals in the first direction in a cross-section which includes the first direction and the second direction, the at least one cooling channel being formed between the first wall section and the second wall section; and
a plurality of partition wall sections disposed in the at least one cooling channel, connecting the first wall section and the second wall section, and forming a wall surface of the at least one cooling channel,
wherein the first wall section, the second wall section and the partition wall sections are integrally formed by additive manufacturing, and
wherein, in the cross-section including the first direction and the second direction, letting t1 be a thickness of the first wall section at a position where a surface of the first wall section which faces the second wall section and a front surface of each of the partition wall sections are connected, the first wall section includes a thin portion having a thickness that is smaller than the thickness t1, the thin portion being at a position away from each of the partition wall sections in the first direction.
