PROBLEM TO BE SOLVED: To provide a combustion type nailing apparatus capable of improving ignition precision of mixed fuel by simple control processing. SOLUTION: A control microcomputer 174, after calculating an appropriate concentration reach time Tx (S203), refers to a voltage value of a battery power supply and gains access to a memory circuit 174a to select a signal output time Tk (S204). After that, in processing of S205, the voltage value of the battery power supply is referred to, an appropriate discharge preparation time Tg stored in the memory circuit 174a is selected and a difference time to be obtained by subtracting the discharge preparation time Tg from the appropriate concentration reach time Tx is calculated. Subsequently, in processing of S206, discrimination processing is executed based on the difference time. According to the discrimination processing, when a calculation result of the difference time is positive, it is determined that an offset time Td corresponds to the difference time and, on the other hand, when the calculation result of the difference time is negative, it is determined that the offset time Td is a fixed time (S206).
