To provide a wall-mounting push pin which can be pushed accurately and reliably into a relatively hard wall such as concrete or a relatively soft wall such as a gypsum board.

First heights of at least two long thin tabular pins 13, 14 belonging to a first group are set higher than second heights of tabular pins 15 belonging to a second group, and therefore, when the wall-mounting push pins 10 are pushed into a wall, only the tabular pins 13, 14 of the first group receive concentrated pushing forces and are pushed into the wall. Subsequently, while being guided by the tabular pins 13, 14 of the first group, pushing by the tabular pins 15 of the second group into the wall is started and the wall-mounting push pins 10 are pushed into to the wall. The wall-mounting push pins 10 can be pushed into the even relatively hard wall stably and reliably while maintaining a posture properly without changing a posture in the midway of the pushing.
