Abstract

A heater device includes a first detection pattern that is arranged on an insulating substrate and detects a change in capacitance between a first transmitting electrode and a first receiving electrode for detecting an object, a second detection pattern that is arranged on the insulating substrate and detects the change in capacitance between a second transmitting electrode and a second receiving electrode for detecting the object, a capacitance determination unit that determines whether one of the change in capacitance between the first transmitting electrode and the first receiving electrode and the change in capacitance between the second transmitting electrode and the second receiving electrode is equal to or higher than a first threshold value and the other is lower than a second threshold value, and a disconnection determination unit that determines a disconnection in the first or the second detection pattern, when result of the capacitance determination unit is positive.
