PROBLEM TO BE SOLVED: To provide an information processor improving safety and reliability, and an error detection method. SOLUTION: The information processor includes: multiple bus slaves; a bus master that outputs address data having a base address value for specifying arbitrary bus slave, and an offset address value for specifying access position in the specified bus slave. The information processor includes: a selection unit that outputs a selection signal for selecting the arbitrary bus slave to the multiple bus slaves according to the base address value output from the bus master; an error detecting code generation unit that outputs an error detecting code from the address data output from the bus master; and an error detection unit that detects an error in the address data according to the error detecting code, which is generated from the offset address value output from the bus master and the base address value for specifying the selected bus slave, and the error detecting code output from the error detecting code generation unit.
