1. A heat pipe structure comprising:
a base block including a rear surface part thermally connectable to a heat generating body; and
a heat pipe fixed to a front surface part of the base block and including a heat receiving tubular portion disposed along an in-plane direction of the base block, wherein
the base block has a longitudinal direction and a width direction and includes a recessed part in which the heat receiving tubular portion is housed and a pair of wall parts projecting along an outer circumferential surface of the heat receiving tubular portion from width direction both sides of the recessed part,
a container of the heat pipe is caulked and fixed by the recessed part and the pair of wall parts and includes a projecting shape part projecting in a direction opposite to a direction of the caulking between distal end portions of the pair of wall parts,
the projecting shape part of the heat receiving tubular portion has a shape corresponding to a shape of a hollow shape part of a caulking jig,
the shape of the hollow shape part of the caulking jig has a curvature, and
a length in a circumferential direction of the projecting shape part in an orthogonal direction to the longitudinal direction of the container is equal to or larger than 5% and equal to or smaller than 40% with respect to an entire circumferential length of the container.
