16. A wall structure comprising:
a building frame of a building;
a plurality of wall materials; and
a securing member for attaching the wall materials to the building frame, wherein
the securing member includes
a substrate portion,
a bulging portion that bulges from the substrate portion in a direction from a rear surface to a front surface of the substrate portion and extends in a longitudinal direction of the securing member,
a contact surface that is provided on the bulging portion and is for coming into contact with a rear surface of the wall material,
a locking portion that extends in the longitudinal direction of the securing member and protrudes from the bulging portion in a direction from the rear surface to the front surface of the substrate portion,
end-side fixing portions that are provided at positions biased toward ends from a center of the locking portion in the longitudinal direction, and in which both sides in the longitudinal direction, and a locking portion side, and an upper side are surrounded by the bulging portion,
a central fixing portion that is provided at a position disposed between the end-side fixing portions, wherein the central fixing portion has a shape different from a shape of the end-side fixing portions,
an inner-side bulging portion that forms a portion of the bulging portion, is located on a side toward the center of the locking portion in the longitudinal direction with respect to the end-side fixing portion, and has a shape in which a side opposite to a side adjacent to the end-side fixing portion is inclined toward the locking portion in a substantially straight line such that width in the longitudinal direction increases toward the locking portion,
an upper bulging portion that forms a portion of the bulging portion surrounding each of the end-side fixing portions, and
one end side of the securing member is fixed to the building frame at the end-side fixing portion, and another end side supports the wall material using the locking portion in a state of not being fixed to the building frame.
