An illumination-type push button device including a board for light source, a diffusing lens having a dome shape, a first light source portion and a second light source portion, and a light guide member, where the diffusing lens is configured such that light of the second light source portion enters the diffusing lens from a back surface, and is diffused from a front surface of the diffusing lens, thereby being irradiated to an outside of the device, and the light guide member is configured such that light of the first light source portion enters the light guide member from an incident surface opposed to the first light source portion on the one end side of the light guide member to be guided inside the light guide member, and exits from an outgoing surface on the other end side of the light guide member, thereby being irradiated to the outside. |
