Un appareil d'entrée tactile (100) comprend une unité de détection d'entrée (31) qui détecte une entrée tactile, sur la base d'un changement de capacité d'une unité tactile (10) par l'intermédiaire de laquelle un utilisateur entre l'entrée tactile, et une unité de réglage de sensibilité (32) qui règle une sensibilité de détection pour que l'unité de détection d'entrée (31) détecte l'entrée tactile. L'unité de réglage de sensibilité (32) règle une sensibilité de détection pour une première région dans l'unité tactile (10) à une première sensibilité, et définit une sensibilité de détection pour une seconde région différente de la première région dans l'unité tactile (10) à une seconde sensibilité qui est supérieure à la première sensibilité. L'unité de réglage de sensibilité (32) permet la coexistence de la première région et de la seconde région dans l'unité tactile (10).
